Rainbow Sugar Explosions That Bounce and Pop
A fun, colorful science-meets-art activity where vibrant baking soda balls fizz, bounce, and pop when vinegar is added. Perfect for engaging kids in creative play!
Ingredients
- 1/2 cup baking soda
- 1/4 cup cornstarch
- food coloring various colors
- water just enough to create a moldable paste
- vinegar in a squeeze bottle or dropper
Instructions
- In a bowl, combine the baking soda and cornstarch. Stir until well blended.
- Divide the dry mix into small cups—one for each desired color.
- Add a few drops of food coloring and about a teaspoon of water to each cup, just enough to create a damp, moldable paste.
- Roll each colored paste into small balls or blobs.
- Let the rainbow balls rest on a tray for 10–15 minutes to firm up slightly.
- Place the balls in a tray or baking dish with raised sides to contain the fizzing reaction.
- Use a dropper or squeeze bottle to squirt vinegar onto the colorful blobs and enjoy the fizzing, bouncing, and popping colors!
Notes
This hands-on experiment is safe and exciting for kids. For even more fun, use glitter or scents in each colored batch. Always supervise young children and place a towel or mat under the tray for easy cleanup.
