Science Bob joins Sheinelle Jones, Dylan Dreyer, and actor Zach Braff on the Today Show for some science experiments.
Check out and try the home version of the Exploding Lunch Bag
experiment from the video HERE.
Science Bob visited the Today Show with John Cena, Tamron Hall, and Al Roker to explore liquid nitrogen, hydrogen rockets, and high voltage electricity.
If you saw my science demonstrations on Jimmy Kimmel Live, and want to learn more, you’ve come to the right place. First, watch the entire segment below:
Oil & Pyrex Glass
While we may think of light traveling at a constant speed, it’s speed can vary depending on the material it is passing through. In fact, light can slow down as much as 50% when it passes through diamonds. How light passes through objects is known as the Index of Refraction. On the show, we demonstrated how light passes similarly through regular cooking oil and Pyrex glass. This means they have a similar index of refraction and so the Pyrex glassware will virtually disappear in the cooking oil.
TRY THIS: If you have some vegetable oil sitting around, fill a container with the oil, (preferably a clear container) and place a Pyrex glass measuring cup in the container of oil. You should see that the glass part of the measuring cup disappears!
Glowing Phosphorus
This awesome demo showed the significance of oxygen when it comes to fire and combustion. The demo uses a deep red powder called RED PHOSPHORUS. Red phosphorus is a flammable powder that burns somewhat slowly. When ignited, you can see it burn and give off smoke. The giant round boiling flask is filled with pure oxygen, and as soon as it is placed over the burning phosphorus, you can see an immediate change as the phosphorus begins to burn vigorously, glow brightly, and fill the flask with a luminous-looking smoke.
This phosphorus demonstration is quite old and historic – it goes back to the 1600s when German Scientist Hennig Brand created white phosphorus by boiling hundreds of gallons of urine in a quest to create gold. Unfortunately, there was no gold in his future, but he did notice the white phosphorus he created would glow, or become “phosphorescent.” White phosphorus, by the way, is much more reactive than its more stable allotrope red phosphorus, which we used in the demonstration.
Liquid Methane Fire
This demo really looked great on camera. Methane gas is a flammable fossil fuel that is commonly used in homes for cooking and heating – it is the main component of Natural Gas. We took methane gas and ran it through a modified copper tube submerged in liquid nitrogen – this cooled the methane below its boiling point, turning it into a very cold, very flammable liquid.
The demo also highlighted something called the Leiden-Frost effect. The best way to think about the Leiden-Frost effect is to consider how cold water on a hot pan skitters around the surface of the pan. This is because it is suspended on a layer of steam as soon as it hits the pan. The same happens with liquid nitrogen and liquid methane – as the cold liquid comes in contact with the much warmer floor of the stage, it instantly begins to boil and spread across the surface. The drops of liquid methane will remain on fire while they vaporize creating a very cool skittering fire effect.
The Tesla-Coil Triggered, Ethanol Powered, Film Canister Gatling Gun
It was time to have a little fun with science. The concept of putting a small amount ethanol into a film canister and triggering it with a spark has been around a while. But I wondered if I could daisy-chain spark gaps to create a device that would blast multiple film canisters in succession. After several tests and tinkering, I found a system that worked using a 6,000 volt Tesla coil for sparks, and wheel made of a material called Gatorboard which was non-conductive and could keep the sparks where I wanted them.
Watch the build and testing in the video below:

What’s it like to be on Nickeloden’s Nicky, Ricky, Dicky, & Dawn? It’s awesome! And in one of my guest appearance, we got to use some real science! Here’s a behind-the-scenes look at the episode, as well as a way for you to try some of the science experiments from the show at home!
In the episode, Mae calls on Science Bob to convince the Harper quadruplets (Casey Simpson, Mace Coronel, Lizzy Greene, and Aiden Gallagher) that there is no such thing as bad luck or curses. This eventually leads to Ricky (Casey Simpson) performing some exciting, yet messy, science demonstrations in the Harper home to prove a point.
So, did the episode use some kind of special effects to create the experiments? No way…the producers wanted to use real science with real chemical reactions!
Dawn’s vinegar and milk experiment will not only make milk chunky, it can turn it into plastic! There’s a bit more to it than you see in the episode, but if you want to try it yourself, CLICK HERE.
WATCH THE CLIP!
Science!
There were no special effects tricks there, that was real science! The “big foamy snake” was actually a dramatic chemical reaction sometimes called Elephant Toothpaste.
In the big flask was hydrogen peroxide, blue coloring and some dish soap. The hydrogen peroxide we used was stronger than the kind you find at the pharmacy, and it can irritate your skin, so Casey’s gloves and goggles were not just for show. When the other chemical, (sodium iodide) was added to the flask it triggered the production on millions of tiny, foam bubbles…and a big mess.
INSIDER INFO:
During the first take of the scene, the foam did not go very high, so the producers asked to try it again. On the second take, (the one they used on the show) the foam went so high, it hit one of the lights in the studio!
The second experiment used the science of food (molecular gastronomy.) When you add Sodium Alginate to a liquid and then put it in some water with Calcium Chloride, you get watery blobs of gel that you can eat!
Casey and Lizzy test out the “olive” experiment
in the Special Effects trailer to make sure it was really science.
But wait, there was some more movie-magic at play during the scene. It one point, the pen in my lab coat had to leak on cue. How did they do that? The Special Effects Department set up very long tube that went from the pen, down my shirt, to a special effects crew member lying down behind the couch on the set. When he heard the cue, he started pushing watery paint through the tube – it worked perfectly.
Want more Hollywood magic? As part of the scene, the handle on my suitcase had to break off at just the right moment. Believe it or not, it was actually triggered by remote control! The special effects crew modified a real suitcase with a special trigger and a receiver. When they wanted it to break, they simply pushed a button on a remote control off-stage.
Science is everywhere, from medical labs, to Mars rovers, to, well, the set of Nicky, Ricky, Dicky, & Dawn.
Never stop exploring!
It was time for some more science on Jimmy Kimmel Live! This visit it was time for some fire, ice, and fun chemistry.
Liquid Nitrogen Powered Bottle Rockets
The first demonstration utilized liquid nitrogen as thrust to power a standard soda bottle. Nitrogen makes up 80% of the air we breathe. And liquid nitrogen will increases its volume 700% when going from liquid to a gas! Because of this, we were able to create pressure without an outside source.
(NEVER place liquid nitrogen in a closed container – many have been hurt attempting this) For this demonstration I custom designed a bottle launcher with several safety features including pressure gauges and blow-out safety valves. Many safety tests were done to test pressure limits of the bottles under several liquid nitrogen conditions as well as launching tests. Ultimately, the pressure needed was far below the pressure limits of the bottle. Eventually I will try this as a vertical rocket with fins and a nose cone.
Briggs-Raucher Chemical Reaction
The cool oscillating reaction used on the episode was called the Briggs-Raucher reaction, named after two high school science teachers in San Francisco who designed the demonstration. It is one of a very small number of chemical color changes that is able to repeat itself multiple times. Solutions include starch, hydrogen peroxide, malonic acid, and sulfuric acid. The reaction is very complex. Even when Briggs and Raucher first developed the reaction, its chemistry was not clearly understood. For those of you chemistry enthusiasts interested in the chemical equation, here is the complete reaction from the MIT Chemistry Department:
The Rubens’ Tube
The last demonstration is called a Rubens’ Tube, named after Heinrich Rubens who demonstrated the device in 1905. A Rubens’ Tube is simply a long metal tube with holes drilled in it a regular lengths. In this case, I drilled 1/16th inch holes spaced 1/2 inch apart, which seems to bring the best results. They can be hand drilled, however I used a milling machine for better accuracy. One end is capped and sealed and the other has a speaker attached. Thin nitrile material seals the end to avoid gas from escaping through the speaker.
As sound travels through the tube, sound waves create peaks and valleys (nodes and antinodes) which change the gas pressure and then affects the size of the flame. A single, even tone can create a great visualization of the sound wave.
The six-tube Rubens’ tube demonstration was created by Michael Dewberry, an amazing fire sculptor with whom I share some shop space with outside of Boston. The size of each tube favors a different frequency allowing the tubes to literally react independently to the same sounds. The effect is mesmerizing.
Hope you liked the demos! Never stop exploring!
WHEN: September 27th, 2015
WHERE?
All of North and South America will be able to witness the eclipse to some degree as well as Europe, South/East Asia, and Africa. The eastern half of the US will get to see 100% of the event while the west coast will see about 60% of the event. (see map)
WHAT’S GOING ON?
During a TOTAL LUNAR ECLIPSE, the Sun, Earth, and Moon all line-up just right causing the earth’s shadow to cross over the surface of the moon. This blocks all the sunlight that usually lights up the moon, causing it to darken in the night sky. The moon turns a dark orange/red color due to the bending of the light as it passes through the Earth’s atmosphere. This is the same phenomenon that gives us orange sunsets.
RARE “SUPERMOON” LUNAR ECLIPSE
The September 27th Lunar eclipse is also a “Super-Moon.” This means the moon is closest to the earth in its orbit and appears larger than usual. A Super-Moon Lunar Eclipse has only occurred 5 times since 1900. If you miss it this year the next opportunity to see a Super-Moon lunar eclipse is not until 2033.
Did you know?
On a recent episode of Jimmy Kimmel (see original clip above) I used a soda bottle to demonstrate a build up of gas pressure. Typical soda bottles are under about 40-60 PSI (pounds per square inch) of pressure when they are bottled. But they are designed to withstand much more pressure – usually around 150 PSI! We decided to put the bottle to the test using liquid nitrogen.
While impressive, this demonstration will show you why you should NEVER EVER use a soda bottle for any kind of experiment involving gases under pressure. The blast is intense, damaging, and loud. We utilized several safety staff, many safety tests, and a box custom built of Lexan (virtually unbreakable) plastic. It is the same material that bulletproof windows are made from.
Because the blast happens so fast, the production brought in a high-speed camera (the Sony NEX-FS700) to shoot the demo at 700FPS.
Since the high-speed clip is brief in the YouTube show clip, here is the extended version. The flickering light is created by the camera picking up the on/off cycle of the LED lights which are usually invisible to the human eye. Enjoy.
Extended High-Speed Footage
This is by far the best way to serve a can of Pringles. Inside of most large rockets is a supply of hydrogen and oxygen. When the mix of the two is just right, it creates an explosion with a huge amount of energy. In rockets, this energy get the rocket into space. In our little demonstration here, it gets the Pringles can to the ceiling.
Here’s how it works:
This impressive reaction is sometimes called, “The Barking Dog.” Watch the video and you’ll see why. It combines a very flammable chemical called Carbon Di-sulfate and the gas Nitrous Oxide. Nitrous Oxide is often used in race cars to give the car a sudden burst of oxygen energy. As the fire travels down the test tube it creates pressure which increases the energy released. After the reaction is over, you can see that the inside of the test tube is covered with a yellow-white sulfur powder left over from the carbon Di-sulfate.

This may just be the easiest, messiest, and most fun science activity I know. It is a classic, and I have gotten several requests recently to post directions. You should know that if you try this activity and you are not smiling and messy with corn starch goo at the end, then you are definitely doing something wrong. Also keep in mind that this is not just about fun, there is some pretty amazing science going on here.
You will need:
Everyone should roll up their sleeves and prepare for some gooey fun.
We’ll get the the science soon, for now just dig in and explore. Notice that the goo does not splash (or even move) if you hit it quickly. Squeeze it hard and see what happens. How long can you get the strands of goo to drip? What happens if you let the goo sit on the table for a minute and then try to pick it up? How does it feel? Hows does it move? Try bouncing a ball on the surface of the cornstarch. You get the idea – explore!
30 minutes later…
So now goo is everywhere and you’re thinking you should probably start cleaning. Actual clean up of the goo is a snap. A bucket of warm water will quickly get it off your hands. It will brush off of clothes when it dries, and it is easily cleaned off surfaces with a wet rag.
Important: Make sure you do not dump the goo down the drain – it can get caught in the drain trap and take the joy out of your day of science. Dump it in the trash, or even mix it into soil in the garden.
Cornstarch grains under the microscope
Now for the science…
Our cornstarch goo (sometimes referred to as “oobleck” from the Dr. Suess book) is what scientists call a “Non-Newtonian” liquid. Basically, Sir Issac Newton stated individual liquids flow at consistent, predictable rates. As you likely discovered, cornstarch goo does NOT follow those rules – it can act almost like a solid, and them flow like a liquid. Technically speaking, the goo is a SUSPENSION, meaning that the grains of starch are not dissolved, they are just suspended and spread out in the water. If you let the goo sit for an while, the cornstarch would settle to the bottom of the bowl.
So why does this concoction act the way it does? Most of it has to do with pressure. The size, shape, and makeup of the cornstarch grains causes the cornstarch to “lock-up” and hold its shape when pressure is applied to it. People have filled small pools with oobleck and they are able to walk across the surface of it (as long as they move quickly.) As soon as they stop walking, they begin to sink.
I hope you get to try this out. Let us know how your day with non-newtonian liquids went. Have fun exploring!
Carving pumpkins is fun, but exploding pumpkins is even funner! While there are lots of ways to explode a single pumpkin, getting many to explode in unison was challenging. This demonstration uses chemicals that create a flammable (acetylene) gas. After much experimenting, I was able to use one exploding pumpkin to trigger the one next to it creating a spectacular chain reaction. This remains one of my favorite Jimmy Kimmel Live demonstrations.
Very few people get the chance to experience the effect of a zero gravity experience. When the team over at the Northrup Grumman Foundation invited me to go up on a zero gravity plane, I jumped at the chance. All they asked is that I think about an interesting experiment to try in a weightless environment. I told them I didn’t have to think about it; I wanted to release 2,000 ping pong balls. Amazingly, they agreed!
Don’t waste your breath.
Why blow up a balloon yourself when you can let chemistry do it for you? Head to the kitchen, grab some baking soda and vinegar and use a classic chemical reaction to inflate a balloon.
>>Click here for instructions to build your own Fizz Inflator <<
This Science/4th of July themed Rube Goldberg Machine chain reaction device took 2 weeks of building and testing. The hardest part (aside from getting it to consistently work) was nailing in over 1,000 nails for the marble drop section. You can’t go wrong in a demonstration that uses chemical reactions, high voltage electricity, an Einstein doll, flammable gases, and a confetti cannon.
Liquid Nitrogen is cold. REALLY cold. -198°C (-321°F) In this demonstration, we literally make a cloud. Adding the boiling water to the liquid nitrogen creates a violent reaction that vaporizes the water. At the same time the effects of the cold liquid nitrogen cause the vaporized water to condense back into tiny drops we call a cloud. This is my favorite all-time science demonstration.
A few years back, on a particularly cold day, the air was filled with static. I went to clean up some tinsel that fell off a Christmas tree and it stuck to my hand like glue. I mean it REALLY stuck. I shokk my hand and it hardly budged. That when an idea hit me. I experimented using a piece of PVC pipe and some tinsel to experiment with static charges. The levitating orb experiment was born. Since then, we’ve mailed out thousands of packs of tinsel through the store (link here) and many of you have posted videos. Here’s the original video:
Here are some of my fan favorites:
Try out the orb yourself (instructions HERE) and make a video. Maybe we’ll add your next!
Would you want to drink green milk, how about orange mashed potatoes? The color of foods might affect just how much you want to eat them, but what about the birds in your neighborhood, would they care what color their food is? This sounds like an experiment in the making…. you coul even try this out for a science fair project, or just to learn something new while making your locals birds happy.
You will need:
QUESTION – What color of birdseed, if any, will birds prefer the most?
RESEARCH: Ornithologists (scientists that study birds) are rather certain that most birds can see in color. One reason they think this is because birds themselves are very colorful. In many species, male birds tend to be more colorful than females. This is likely because the males use their coloring to attract a mate, while female birds tend to have less coloring to provide camouflage as they protect their eggs in the nest. Before beginning a large experiment with lots of bird seed, you may want to put out a few small handfuls of different colored birdseed (see instructions for coloring birdseed below) to see how the birds near you react to different colored seed. You may also want to refer to books and talk to an ornithologist to get their opinion about how birds see the word.
MAKE A HYPOTHESIS: Use the information that you’ve gained from your research and make a hypothesis based on your question. An example might be “Birds will eat more green birdseed than other colors.”
EXPERIMENT: This is the fun part. You should get several bird feeders that are all the same size and type. Purchase a bird seed that is very light in color for this experiment. To color the bird seed, pour it into a bowl and then add food coloring that you can purchase from the store. Mix it up well with a spoon and continue to add color until all the seed is colored. You should sample at least a few colors and have one feeder with seed that has not been colored – this is called the control and it will give you something to compare your results to. Now just hang them up outside in the same location, and wait for your feathered friends to show up. This works best in an area that birds are used to feeding from a feeder – it can take birds over a week to find new feeders.
COLLECT DATA: Observe your bird feeder whenever possible, and keep track of how much seed is in each bird feeder each day. A ruler is helpful for this. You might also want to take pictures of the feeders and keep track of which kind of birds visit each feeder. Over time, you should be able to see if one color of seed gets eaten more than others.
MAKE A CONCLUSION: Once your experiment is done, you will be able to go back to your hypothesis and see if it is correct. Remember,it’s not bad if your hypothesis was wrong. The main thing is that you’ve learned something from your experiment, and hopefully you had some fun doing it.
If you try this, let me know how it goes!

In many parts of the world, autumn is a time for leaves to turn dramatic bright colors. Most of those spectacular colors of autumn have actually been in the leaves all summer, however they were “covered up” by the dominant green of the chlorophyll. As weather cools, and shorter days settle in, the leaves are no longer able to produce food for the tree. The chlorophyll begins to break down, revealing new and varied color pigments. The brightest colors are seen when late summer is dry, and autumn has bright sunny days and cool nights.

Kari Wilcher runs a great blog. She was looking to teach her pre-school children about the Scientific Method while trying out some kitchen chemistry at the same time. Her plan was to show a dramatic acid-base reaction using lemons, baking soda, and a little dish soap. She writes:
“I firmly believe that children are never too young to be exposed to the scientific method and should follow it. I have found that the scientific method is very easy for them to understand, and follow, when presented to them in a simple way. I like to use a rebus (picture) to help my non-readers understand the directions. I also use these “big” words: data, hypothesis, prediction, and observation. We, including Momma, wear goggles (from the dollar store) and a lab coat (a.k.a. dad’s white button up shirt) because we are real scientists doing real science experiments…and it just makes us cool.”
You will need:
What to do:
How does it work?
This is a classic example of an acid-base reaction. This is often done with vinegar and baking soda, but we liked Kari’s “lemon twist.” The baking soda (a base) and the lemon juice (an acid) combine to release Carbon Dioxide gas. The liquid soap turns the bubbles into a foam that often erupts right out of the glass.
Try it out and let us know how it goes!
This is so simple, and so cool. It uses static electricity to make a tinsel orb levitate above a PVC pipe. We’ve gotten the orb to float for over 10 minutes. We just discovered you can use a regular balloon instead of the PVC pipe, but we like the pipe best. Watch the video, and then make your own!
One of the best parts of sharing experiments on this website is hearing back from people that get to try them out. I was happy to recently find out that the young actors that appear in the movie, The Little Fockers were fans of sciencebob.com.
Even famous child actors have to go to school every day, so film and TV productions set up a special room or trailer that gets used as the classroom while the filming is going on. A teacher is on the movie set every day to teach lessons in between filming scenes. While this film is targeted for adults, we were happy that some great science lessons were going on behind the scenes with the young actors. The lessons were led an amazing teacher named Maura who enjoys exploring hands on science and bringing learning to life. Maura was kind enough to contact me and send us some behind-the scenes photos from the set of the movie.
Daisy Tahan plays Samantha Focker in the film. She’s been acting since she was just 4 years old. In this picture she is trying out our experiment titled “The Fizz Inflator” which allows you to inflate a balloon using only the power of chemistry. As you can see it was quite a success for Daisy. To try out the experiment yourself, just click HERE.
Daisy also experiment with non-newtonian fluids when she created oobleck using corn starch and water. In the right combination, these two ingredients make very unique goo that can act like both a solid and a liquid. (If Daisy’s hands look a little blue in any scenes of the movie, now you will know why.)
Daisy and fellow actor Colin Baiocchi, who plays Henry Focker in the movie, confirm what famous scientist Archimedes observed hundreds of years ago regarding the displacement of water when an object is placed in it. The graduated cylinder with the green water allowed them to measure how much the water was raised when different objects were placed in it.
Maura reports the two actors also got to try out our film canister rockets. We’re happy that our experiments were able to provide some fun and learning on a backlot in Hollywood as much as they are in classrooms and living rooms around the world. Thanks again, Maura!
We’d love to see YOUR pictures of our experiments in action. We may post them right here on our blog. You can email them to [email protected].
I’ve always been a fan of science activities that you can eat. One of my favorites is the Oreo Cookie Moon Phases activity. It’s almost as if Oreo cookies were made for this lesson, and it’s a great way to learn how to match a moon phase name with a moon phase appearance.
You will need:
What to do:
Separating Oreo cookies while keeping the frosting intact is a fun challenge. I like to slowly twist the Oreo to maximize the amount of frosting on one side, Cooling the cookies in the refrigerator can make it easier, but then you wouldn’t be able to eat the mistakes.
After twisting, hopefully most of the frosting will be on one side or the other. You can always transfer frosting if needed.
Use the above image, (or download the PDF below) to show how the moon changes from new moon, to full moon, and back every 28 days. Recreate each phase in cookies and frosting, and then snack on the results. Science is yummy.
Bubbles may very well be the world’s first toy. From sea foam, to hand soap, to those bubbles you blow in your milk, it seems bubbles are part of our daily life. Soap bubbles way be the most fun off all bubbles and they are an inexpensive and limitless way to explore our bubbly world.
For years bubbleologists have perfected the solution for the longest-lasting and most durable bubbles. Perhaps the person who has studied the science of bubbles the most, is Keith Michael Johnson. And he recently shared his unlikely TOP-SECRET formula for the best bubble solution…
Water – many bubble enthusiasts are convinced that distilled water makes the best bubbles
Liquid dish soap. Dawn dish soap has always been a favorite
SurgiLube (available at medical supply stores) or K-Y Jelly (available at pharmacies)
A clean plastic bottle to hold your bubble solution
Simply pour all three ingredients into the bottle in the following ratio:
12 parts water
1 part dish soap
1/2 part SurgiLube
For example you would start with 12 ounces of water, add 1 ounce of liquid dish soap, and 1/2 ounce of SurgiLube. You can increase the amounts equally to make more.
Shake the ingredients up well (don’t worry, the bubbles from shaking will go away)
For best results, allow the bubble solution to sit overnight. Then you’re ready to go!
How do bubbles work?
Every soap bubble is made of a film that has 3 layers: Soap, then Water, then Soap. Because of the way that soap molecules are arranged, and the way they attract and repel from each other and the water, the soap creates bonds that give the water additional strength, and allow them them to last much longer. Bubbles will always be round when they are floating because the elastic nature of the soap bubbles allows air pressure to push equally on the entire surface of the bubble forming a sphere.
Bubble fun:
You do not need bubble wands from the store to make bubbles. Simply dipping your hand in bubble solution and making a circle with your fingers makes a great bubble wand. Straws, plastic strawberry containers, fly swatters, and aquarium nets make great bubble wands.
To make foamy bubbles, use a rubber band to secure a piece on cotton cloth over the end of a small section of plastic pipe. Soak the cloth in the bubble solution and blow from the other end.
Pour a small amount of bubble solution onto a clean counter top and spread it out. Use a straw to blow a dome-bubble on the counter top. Keep blowing into the bubble to make it bigger and bigger. With some practice, you can get a bubble dome as big as a dinner plate!
If you want to make any day better, perhaps the easiest way is to add bubbles to it. We have seen lots of different kinds of bubbles: big bubbles, small bubbles, bubbles that don’t pop, even colored bubbles. But my personal favorite is Ghost Bubbles. They’re not that hard to make and they are great fun to explore…especially at Halloween:
You will need
CAUTION!: NEVER touch dry ice with your bare hands.
Always wear thick gloves and keep away from children.
NEVER place dry ice in a completely enclosed container.
What to do
MORE GHOST BUBBLE FUN:
Try holding Ghost Bubbles with a fuzzy glove such as a wool glove. With some practice, you can toss and bounce the bubble.
Allow the bubbles to fall onto a fuzzy surface, such as a towel. Try rolling them around by lifting different ends of the towel. Fuzzy surfaces keep the bubble from easily popping because they spread out the amount of pressure on the surface of the bubble, and keep it from touching a surface that would absorb the moisture and dry out the bubble, causing it to pop.
GHOST BUBBLE INFO:
Every soap bubble is made of a film that has 3 layers: Soap, then Water, then Soap. Because of the way that soap molecules are arranged, and the way they attract and repel from each other and the water, the soap creates bonds that give the water additional strength, and allow them to last much longer. The dry ice mist is a combination of water vapor and carbon dioxide gas from the dry ice. Because carbon dioxide is heavier than air, dry ice mist will always flow downward.
