Dancing Worms Experiment
Grab a couple of easily accessible items from your pantry and let some gummy worms give you and your family an entertaining science lesson about density and buoyancy. Kids of all ages will be intrigued by the little show that the colorful worms will put on before their eyes as they watch this experiment unfold.
How To Do It
The gummy candies are much denser than the solution that they are in, therefore they fall to the bottom of the liquid. The vinegar and baking soda cause a reaction that releases carbon dioxide which adheres to the rough surface of the worms which increases the buoyancy of the candy and makes it rise to the top. When the gummy worm slices reach the top of the liquid, the carbon dioxide gas is released into the air and they again sink down to the bottom of the glass until more CO2 bubbles attach themselves again and make their way to the top.
