- Combine equal parts glue and liquid starch, mix well.
- Add Borax solution (plus food coloring and/or glitter if you’re using it) to the glue/starch mixture. Mix very well.
- When the mixture becomes too stiff to mix with your spoon, use your hands to knead it into a rubbery blob. Your putty will probably need to dry a little before you can play with it.
- Cooling the putty slightly should make it more “bouncy,” but if it gets too cold it will shatter. Store your funny putty in a resealable sandwich bag or other air-tight container. Funny putty usually lasts about two weeks.
