Dancing Jelly Worms

Method

Bring jelly worms to life with this fun experiment using ingredients from your cupboards. The best part? You can enjoy the rest of the jelly worms in the packet while you watch them dance!

The Science:

The baking soda in the jelly worms acts as a base, which neutralises the acidic vinegar. This causes carbon dioxide gas bubbles to form around the jelly worms, making them wriggle to the surface. Once at the top, the carbon dioxide can escape into the air, but the jelly worms drop back into the glass. When they have enough bubbles around them again, they can rise back up!

---------------------------------

  1. Depending on the length of your jelly worms, you may need to cut them up so they’re around 2 inches long. We’d recommend using around 4 pieces of jelly worm for this experiment.
  2. Fill a clear glass with the warm water. Add the baking soda into the water and stir well until fully mixed together.
  3. Place your jelly worms into the water mixture and set the glass aside for around 15 minutes, allowing the baking soda to soak into the worms.
  4. Fill another clear glass with the vinegar.
  5. Take your jelly worms out of the water mixture and drop into the second glass of vinegar.
  6. After sinking to the bottom of the glass, bubbles should start forming around your jelly worms and cause them to ‘dance’ to the top of the glass!
  7. Your jelly worms will keep dancing until all the baking soda has disappeared.
