This Christmas Tree fizzy science experiment is pretty simple. To get started, prepare your space with a table cloth, or even better, a cookie sheet or other shallow tray. You want to contain the mess, because all fizzy science is MESSY! The mess is half the fun!

This experiment uses the classic chemical reaction between vinegar, aka acetic acid, and baking soda. The acid and the base (baking soda) react in a low-energy reaction that releases carbon dioxide gas and water (and sodium acetate).
The gas travels through the water, creating the bubbly mess we all know and love.
Unique to this experiment is the beads and the cookie cutter. This is what will give you the Christmas Tree “look”. When you use an eye dropper to control the reaction, and start at the “top” of the tree, you’ll end up with bubbles surrounding beads, that look like a Christmas tree decorated with ornaments.
It’s a very cool effect, and one your kids are sure to love!
Try this with other cookie cutter shapes! What about a Snowman, with black and orange beads for the face and buttons? Or a “Gingerbread” snowman with colored beads for his face? Are there other combinations you can come up with? Share your results in the comments and inspire others!
