Alternate Idea: Use Christmas theme cookie cutters on a tray instead. It will be a bit messier!

Supplies:

• Small Clear Cups (or cookie cutters)

• Baster or Eye Dropper
• Glitter
• Tray

Set-Up

STEP 1. Set out a tray to catch the fizz! This mini Christmas baking soda eruption can get a little messy! It is an eruption, of course.

STEP 2. Place as many cups as you like on the tray.

STEP 3. Add baking soda {1/2 tablespoon or so} to each one.

STEP 4. Add a few drops of food coloring to each one and sprinkle with glitter.

STEP 5. Set out a bowl of vinegar and an eyedropper or baster. Use the baster or eyedropper to squeeze vinegar into the cups and see what happens!

Try this with plastic ornaments! Take a look at our erupting Christmas ornaments setup.

With each little cup, kids are rewarded with colorful and glitter-filled mini Christmas baking soda eruptions! The color is a surprise if they didn’t help you set it up!

Setting up mini eruptions allows your kids to explore again and again. Keep a lot of vinegar handy! They will definitely want to keep the eruptions going on and on!
