Wack-A-Packs are fun favors that are perennial favorites for the holidays. So what’s inside that makes it inflate?
Remember those grade school science projects that made a volcano erupt? That’s what a wack-a-pack is! Just 3 simple house hold ingredients:
- Baking Soda (sodium bicarbonate)
- Vinegar (citric acid)
- Distilled water
The simple reaction when the ingredients are mixed together is what makes the bag inflate. Just wack the pack on a steady flat surface to activate.
