A fun experiment to encourage children's interest in science, for this we will need the following materials.


  • Gummy worms, gummies or as they tell you in your country.
  • Bicarbonate
  • Vinegar
  • Water
  • 1 transparent glass


This is how it is done.

First cut the worm lengthwise into four pieces and place them in a full glass of warm water with three tablespoons of baking soda for 15 minutes.Then remove the worms from the glass with a fork and insert them into another glass with vinegar. In a matter of seconds the worms will begin to cover with bubbles and climb twisting towards the surface.

I explain, how all this works!

When joining worms impregnated in baking soda with vinegar occurs a chemical reaction that causes the formation of gas bubbles (carbon dioxide) around the rubber worm, which immediately rises to the surface.
Once the gas bubbles burst, the worm falls down and is covered again with bubbles that make it rise again, and so until one of the two reagents (bicarbonate or vinegar) is exhausted.
