My oldest son made this before at summer camp and when he saw I had the Borax out the other day making my homemade laundry soap, he's like "Mom, can we make slime?" Sure! We had to find some glue in the house but we found a bottle I had got super cheap with coupons when school started so we made green slime!
Materials
- Elmer's white glue or Elmer's school glue gel
-
Borax (find in the laundry detergent aisle of the store)
- Water
- Two bowls
- Food coloring (optional)
What to do:
- In one bowl mix 1/2 cup (4 oz) glue and 1/2 cup water.
- In the other bowl, mix 1 teaspoon borax with 1 cup water until the borax is
dissolved.
- Add the glue mixture to the borax solution, stirring slowly.
- The slime will begin to form immediately; stir as much as you can, then
dig in and knead it with your hands until it gets less sticky. (No one makes
slime without getting a little messy!) Don't worry about any leftover water in the bowl; just pour it out.
- Put the slime in a plastic bag and add a few drops of food coloring. Squish it around in the bag and it will magically turn colors! (Brody chose green)
What's happening?
The glue has an ingredient called polyvinyl acetate, which is a liquid
polymer. The borax links the polyvinyl acetate molecules to each other, creating
one large, flexible polymer. This kind of slime will get stiffer and more like
putty the more you play with it.
Store it in a plastic bag in the fridge, to keep it from growing mold.
