This simple kids’ science activity is perfect for little mad scientists who like seeing creatures come alive before their eyes. This kids’ science experiment uses baking soda and vinegar to make gummy worms dance.
- Gummy Worms
- Baking Soda
- Cutting Board
- Sharp Knife
- 2 Clear Cups
- Cut the gummy worms in quarters.
- Measure out 3 tablespoons of baking soda and stir them into a glass filled with 1 cup of warm water
- Mix the worms into the baking soda and water concoction.
- Wait 15 minutes for the worms to soak in the baking soda mixture. Fill the second clear glass with vinegar in the meantime
- After 15 minutes, fish out the worms with a fork. Placing just a couple worms in the vinegar: they should instantly start bubbling and writhing their way to the surface.Explanation: When you add the worms soaked in baking soda, the acetic acid in the vinegar reacts with the bicarbonate in the baking soda. When an acid and base react carbon dioxide gas bubbles form. These gas bubbles form on the gummy worm and as the gas bubbles rise to the surface, they pull the gummy worm up with them, making them wriggle and dance. As the gas bubbles burst, the worm falls back down until enough bubbles form to pull it back up. The bubbles will continue to form until all the baking soda on the worm is used up and the worm will stop wiggling.
