Burp In A Bag

Learn how to make a burp in a bag with this chemical reaction science experiment that is easy, fun, and loud.

 

Materials:

  • Tissue
  • Tape
  • Vinegar
  • Ziplock sandwich baggie
  • Safety goggles

 

Instructions:

  1. Put about one tablespoon of baking soda onto a square of tissue.
  2. Fold the tissue into a little bundle and secure with tape.
  3. Head outside as the next step can get a little messy.
  4. Add about a half cup of vinegar to the ziplock sandwich baggie. 
  5. Drop your tissue bundle of baking soda into the bag and zip the bag closed quickly.
  6. Toss and observe as your burp in a bag grows and eventually pops!

How it Works:

The vinegar and baking soda create a chemical reaction that releases carbon dioxide. The carbon dioxide gas builds up in the ziplock bag until the pressure causes the bag to pop. 

 

Make This A Science Project:

Test different types of ziplock bags and brands to see if there are any observable differences. Try increasing or decreasing the amounts of baking soda and vinegar.
