Lara runs a homeschooling blog from her home in Arkansas. One day, she gathered her kids and all the materials to make slime but she did not tell them what they would be creating. Using a familiar recipe, the boys were soon measuring, mixing, stretching, and yes, even learning about types of matter and polymers. Here’s Lara’s proportions for her large batch of slime. (See link below for smaller batches and to get some information about the science of polymers)
- 1 8-ounce (240 ml) bottle of glue
- 2 cups of (480 ml) warm water, divided
- food coloring
- 1 1/2 (8 ml) teaspoons Borax powder
- bowls for mixing
Pour the whole bottle of glue into a big bowl then fill the empty bottle with 1 cup of warm water and add that to the glue. Stir it up until it thins out.Then add several drops of food coloring and mix that in.In a separate bowl mix the Borax and the second cup of warm water until the Borax dissolves.Stirring CONSTANTLY, slowly pour the Borax into the bowl of glue. Stir and stir and stir until it forms into a goopy, slimy, mass. Remember to store it in an airtight container or it will dry out.
