Materials:
- Pan or Bowl
- Baking Soda Pouches (1 rounded tbsp baking soda, in a piece of single ply toilet paper)
- 1 quart vinegar (1/4 cup or 75mL per group)
- 1/3 cup measuring cups or 25mL graduated cylinders
- Ziploc sandwich bags
Instructions:
- Make a baking soda pouch… Measure 1 rounded tablespoon of baking soda into a square of single ply toilet paper. Fold and secure with a small piece of tape. Make 1 per bag.
- Open bag slightly, allow empty portion to hang over edge of pan and add baking soda pouch so that it does not touch vinegar
- Zip bag shut without mixing the pouch and the vinegar yet.
- Lift bag, allowing chemicals to mix. Shake 3 times, place in pan/bowl and observe what happens!
How It Works:
When the baking soda and vinegar mix, it results in a chemical reaction that produces carbon dioxide (CO2) along with water (H2O) and sodium acetate. If the bag is properly sealed, the carbon dioxide is trapped and fills the bag until it cannot hold any more, at which point it pops!
Add Color and a hole once the bag fills for a fun new element!
