Fizzing Christmas Trees

In our home (and with the Tiny Tots in my classes), baking soda and vinegar NEVER get old.  All the fizzing and bubbling and color changes make it a fun activity anytime.  So, how about making a few Fizzing Christmas Trees to get in the holiday spirit?  My superheroes and the Tiny Tots had a blast with these!

Here’s what you need to get started:

  • Baking Soda
  • Water
  • Measuring cup
  • Large Mixing Bowl
  • Paper plates cut in half
  • Glitter, Sequins, Beads, etc… (anything you’d like to mix in to your trees)
  • Vinegar
  • Green food coloring or green liquid watercolor
  • Bin to contain the mess

To make the fizzing Christmas Trees:

Add 2 cups of baking soda (about one 1lb box) to a large bowl.  Add glitter, beads, sequins (not necessary but always fun).  IMG_4477

Add the food coloring to 1/2 cup of water and place in the bowl.

Cut a paper plate in half.  Roll it into a cone shape and tape the sides.

Trim the bottom of the plate and flatten the top so that you don’t have leaning trees (like some of mine!)

Place in the freezer overnight to firm up the shape.

The next morning, the trees were very hard. Perfect!

To play: 

Unwrap the paper plate from the trees and place into a bin.  I added some baking soda on the bottom to look like snow.

I had my superheroes add a little “snow” to the trees.

I gave them 2 cups of “Elf Potion” (vinegar with red and green food coloring) and a dropper.  They knew EXACTLY what to do!

The instant the vinegar hit the trees, the fizzing and bubbling began.

As the trees “melted”, they found beads and sparkly glitter.  The older ones kept at it until the tress were all gone and a sloppy, glittery, goopy mess was left as evidence of some fun holiday science!

Bubbles and fizzing!!!  They LOVED it!!

Such an easy and simple little experiment to set up with a Christmas twist.  For more ideas on how to play with baking soda and vinegar throughout the year, check out my other fizzy activities:

Science Behind the Activity:

This is a twist on the classic baking soda and vinegar experiment.  Baking soda is a base and vinegar is an acid.  When combined, they release carbon dioxide gas (the bubbles).  The fizzing and bubbles are just way too much fun for the kiddos!
