Chemistry is a blast with this backyard bomb...made from a simple sandwich bag. All you need are a few ingredients from the pantry to create a satisfying, and safe, explosion.
Kids get an early introduction to the wonders of chemistry, by watching what happens when vinegar and baking soda react. The carbon dioxide created by mixing these everyday ingredients fills the bag until there's no more room for expansion, then explodes with a dramatic boom.
What You Need:
- paper towels
- sandwich bag that seals completely and has no holes
- 1/2 cup white vinegar
- 1 1/2 tablespoons baking soda
- 1/4 cup warm water
- scissors
- a clear outdoor area
