Fizzy Olympic Rings

Fizzy Olympic Rings


If the sheer amount of Olympic posts I have on this blog isn’t an indicator of how much I love the Olympics, I am not sure what is! A few weeks ago we participated in “A Very Toddler Olympics” and now we are participating in the Kid Blogger Network Olympic Activities round-up. These Fizzy Olympic Rings are perfect for incorporating STEM (or STEAM) learning into your Olympic thematic unit!




Here’s what you’ll need:

Baking Soda


Liquid Watercolors OR food coloring

Squeeze Bottles

Safety Goggles



Safety Note:  Both baking soda and vinegar can be painful and dangerous if they end up in your child’s eyes. My kids refused to wear the safety goggles but I would highly recommend them. If your child chooses to put her hands in the mixture (like mine did), wash her hands thoroughly afterwards. Like all activities shared on this blog, please make sure you supervise your child during the entire activity.



1. Mix together baking soda and a small amount of water. Add more water and stir until the baking soda has formed a paste or dough-like consistency.

2. Form the baking soda/water dough into circular shapes to resemble Olympic Rings. Place in the freezer for at least an hour.




3. Pour vinegar into each of the squeeze bottles and then add liquid watercolors or food coloring into the vinegar. I used liquid watercolors and the end result ended up being very muted, so next time I might use food coloring instead.

4. Get the tray with the Olympic Rings out of the freezer and gather your colored vinegar bottles.

5. Head outside and get ready for some fizzy fun!



6. Let your child(ren) start spraying each of the Olympic rings with the coordinating color. Watch the reaction of the baking soda and vinegar!
