Here’s what you do:
- Combine ½ cup water with one teaspoon of Borax in a cup and stir with a popsicle stick.
- In another cup, mix equal parts white glue and water.
- Add in a glob of glue mixture to the borax.
- Stir for one second with a popsicle stick, then quickly pull the putty out of cup and play with it until it dries enough to bounce on table (3-5 minutes).
