Want a scary something for your Halloween party?

Have a look at this spooky experiment from The Kitchen Pantry Scientist.

What you need:

  • Gummy worms - you can get these from a supermarket or pick n mix
  • Scissors
  • Baking soda
  • Vinegar
  • Water
  • Clear glass
  • Fork

What to do:

Make sure you ask an adult for help cutting up the gummy worms.

  1. Cut the gummy worms in quarters lengthways.
  2. Put three tablespoons of baking soda into a cup of water and stir.
  3. Put the gummy worms in the baking soda solution and let them soak for 15 minutes.
  4. Fill the glass with vinegar. Use a fork to lift the worms out of the baking soda solution and put them into the glass of vinegar.

What can you see?

What's happening?

Your worms should start to float and move up and down. The vinegar reacts with the baking soda to form carbon dioxide gas bubbles on the worms. The carbon dioxide gas bubbles rise up through the vinegar and cause the worms to wriggle. The worms will wriggle until the reaction stops!
