How To Make A Baking Soda Volcano:
My daughter and I made a baking soda volcano the other day and, pardon the pun, it was a blast!
She was home sick so we had plenty of time to make our version of Mt. Fuji, complete with an ecosystem of trees, flowers, and shrubs. We then set off a series of baking soda volcano eruptions so impressive that she hasn’t stopped talking about it since.
How to Make a Baking Soda Volcano
MATERIALS
· A plate, platter or dish for the base
· 1 quart mason jar or soda bottle
· Playdough (you could also use salt dough or aluminum foil)
· Nature items like flowers, sticks, leaves, and pebbles
· Lava (see instructions below to make your own lava)
INSTRUCTIONS
Step #1. Build a Playdough Volcano
First, we shaped the volcano by wrapping lavender playdough around a quart glass mason jar.
I’d wanted to make a volcano out of papier mache, but since this was a last-minute project we used what we had on hand, which was a batch of no-cook playdough. I’ve also heard of people mixing a quick batch of salt dough to use for this purpose, or just crumpling aluminum foil around a soda bottle for the mountain.
After molding all of the lavender playdough around the jar, we decided to cover the platter with the rest of the playdough we had in the house.
Quite an artful volcano, no?
Step #2. Add Nature Landscaping
Then we added landscaping to Mt. Fuji. We poked various nature items into the playdough to create trees, flowers, and bushes, much like we did when we created a forest diorama on our kitchen table. We also included pebbles for boulders and made a bridge out of sticks.
Step #3. Make the Baking Soda Volcano “Lava”
I followed this tutorial I found on Weather Wiz Kids for the quantities of baking soda, etc. When I was a child, we made our volcano with just baking soda and vinegar, but this tutorial calls for a little more and I think it was worth doing.
Here’s how…
MATERIALS
· 2 tablespoons baking soda
· Dishwashing detergent
· Red food coloring
· Vinegar
· Warm water
INSTRUCTIONS
First, we mixed red food coloring with warm water…
Then we poured it into the jar hidden inside the volcano. We added six drops of dish soap, two tablespoons of baking soda, and then the vinegar.
The eruption was awesome! The baking soda volcano reaction was bigger than I expected and it happened so quickly that I didn’t photograph it quick enough.
I also wasn’t expecting the overflow, so we wrapped towels around our platter to catch the “lava.” Then we proceeded to set off a total of seven volcanic eruptions in our kitchen!
Who knew such fun times could be had while wearing pajamas in the middle of a sick day?
