Make a Volcano with Off-Kilta Matilda™

Make a Volcano with Off-Kilta Matilda™

We had fun making a volcano in our backyard!

Here is a short clip we put together to show you how to do it too. We did this with the help of middle school kids—they got to make a volcano and make a video on how to make a volcano. We can integrate learning into many of our summer activities—STEM is in!

 

To make your own volcano, you will need a few supplies:

  • Soda bottle (16 or 20 oz.)
  • 1 tablespoon baking soda
  • 1 cup vinegar
  • Red food coloring

If you want to add bubbles to your volcano just add a bit of dish soap to the mix!

We went a bit crazy and used everything from moss to rocks to decorate our volcano—you can do as little or as much as you want.

Experiment

  1. Place the bottle in the middle of a flat surface. You can use a table, driveway, or patio.
  2. Put found materials around the bottle to make it look more like a real volcano or mountain. We used cardboard and tape and covered that with grass and moss. You can use dirt, rocks, and flowers—get creative!
  3. Pour the baking soda into the bottle.
  4. Add the red food coloring to the vinegar.
  5. Pour the vinegar into the bottle—we used a funnel to make sure it got in without making a mess.
  6. Stand back and watch the red “lava” flow!

We had a good time adding different measurements of baking soda and vinegar to see what would make the biggest explosion. Take notes and see what works the best for you!
