Rainbow Fizzies STEAM Activity
written by: Brittney Dowell
- Muffin tin
- Colorful silicone muffin cups (or food coloring)
- Baking soda
- Glo Pals
Line your muffin tin with colorful silicone muffin cups. Alternatively, you can also add in a drop of food coloring instead of the muffin cups to add some color to your experiment!
Fill each muffin cup with a Tablespoon of baking soda
Place Glo Pals in each muffin cup for extra fun!
Fill each cup with a little water. You may need to wiggle the Glo Pals a little bit to get them to light up. You can also add in a drop of dish soap (this will give your concoction extra bubbly fun!)
Add lots of glitter (...this may be our favorite step.)
Using a dropper and a bowl of vinegar, have your little one add vinegar to each muffin cup and watch the fizzy rainbow appear! You can turn off the lights and watch your pals fizz and glow!
Let's talk science, Pal!
Wondering what just happened? You just experienced a chemical reaction (in colorful bold). Vinegar is an acid (colorful bold), and baking soda is a base (colorful bold) - when the two react, we get carbon dioxide (colorful bold) In fact, those teeny tiny bubbles that you see as rainbow fizzies, are actually lots and lots of CO2 molecules!
