Fab Family Fun: Erupting Volcano

Today’s idea is not mine.  It was taken from kaboose.com.  And guess what?  I don’t have to buy anything to make it!  I bet most of you won’t either.  I don’t actually have any 3 oz paper cups, so I’ll just cut one I do have to make it shorter.

Erupting Volcano

For the Volcano, You Will Need:

Large paper plate
Bathroom disposable cup (3 ounce is best)
Aluminum Foil
Scotch Tape

To Make the Volcano Erupt, You Will Need:

Baking Soda
A Cup
A Pan or Tray

To Make Your Volcano Erupt:

  1. Place the volcano on a pan or tray (or you’ll get lava all over the place!)
  2. Fill the volcano with 2 tablespoons of water and stir in a tablespoon of baking soda until it dissolves.
  3. Measure 2 tablespoons of vinegar into a separate cup.
  4. Pour the vinegar, all at once into the water/baking soda mixture and watch your lava bubble up!

Why Did That Happen?

The bubbles that are created are filled with carbon dioxide.  Carbon dioxide is a gas that forms when the vinegar (an acid) reacts with the baking soda (a base). For all you bakers out there, this is also what makes cakes and quick breads (the no yeast kind) get all nice and fluffy.

Monica just showed me this site last week, and I’m loving it!  For more ideas, click on craft videos to the right of the main page.
