Exploding Bag Demonstration
Ziploc bag (make sure it is leak free)
Vinegar (1/2 cup)
Baking Soda (1 Tbsp)
1. Place the baking soda in the middle of the paper towel. Fold the paper towel into a square, with the baking soda now inside the square.
2. Pour vinegar into ziploc bag.
3. Seal the bag at least halfway.
4. Add the baking soda packet into the bag and quickly zip it closed.
5. Shake the bag a little, then place it on the ground and step back.
6. The bag should explode!
If this doesn't work, your bag may have a leak, or you may want to try a smaller baggie (or add more ingredients). Make some adjustments and try again.
What happened with the baking soda and vinegar?
Has anyone seen these two substance react before? (Maybe in a volcano model)
What caused the bag to explode? (The reaction produced gas (carbon dioxide) which expands and needed to escape)
What could you conclude about interactions between acids and bases from this demonstration?
