Waggling Worms



You will need:

  • Spaghetti
  • Crystal clear bowl
  • 1 cup of vinegar
  • 1 cup of water
  • 2 tablespoons baking soda
  1. Cook the spaghetti. Let it cool and then cut a few strands of spaghetti into 1 1/2 inch pieces.


2. In the bowl, mix the cup of vinegar and the cup of water.



3. Add a few drops of red and blue food coloring.




4. Slowly add the 2 tablespoons of baking soda.



5. Now drop the pieces of cooked spaghetti into the bowl.


What will happen?
It will look like worms are waggling back and forth!

Why?
The vinegar and baking soda forms a gas bubble, which makes the spaghetti lighter to rise to the surface. Once on top the bubble break open and the spaghetti fall back. And then the process is repeated.
