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 […]

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 […]
