Science Saturday - It's Alive!!!

Want to make gummy worms come alive?  Follow these simple instructions. 

What you need:

  • Gummy Worms
  • Scissors
  • Baking Soda
  • Vinegar
  • Water

Cut gummy worms lengthwise to make some super skinny worms.  Mix a few tablespoons of baking soda with a cup of water and stir in gummy worms.  Let soak for 15 to 20 minutes.  Fill a clear glass with vinegar.  Drop the worms in and watch them squirm.

Why does this work? 
Vinegar is acetic acid CH3COOH and baking soda is sodium bicarbonate NaDCO3 (a base).  When they mix they create carbon dioxide gass bubbles on the worms. NaHCO3 CH3COOH --> CH3COONa H2CO3  The H2CO3 is carbonic acid which will quickly break down into H20 (water) and CO2 (Carbon Dioxide).
