Make Your Own Erupting Volcano

by jenni on August 18, 2010


Since school has begun, I thought this week I would celebrate it by doing an educational craft. I love science so making a simple erupting volcano was perfect. It is the perfect craft to teach kids with because it has a little bit of everything from geography to chemistry. Plus it is something fun to watch.

Materials Needed:

For the Volcano:

  • Large paper plate
  • Bathroom disposable cup (3 ounce is best)
  • Aluminum foil
  • Scotch tape
  • Scissors

To Make the Volcano Erupt:

  • Water
  • Baking soda
  • Vinegar
  • Tablespoon
  • Cup
  • Pan or tray
  1. Attach the paper cup to the plate by taping the bottom of the cup to the middle of the plate.
  2. Tear off a piece of foil large enough to completely cover the cup and plate.
  3. Place the foil over the cup and plate and turn the foil under the plate edge.
  4. Tape the foil in place.
  5. Poke a hole through the foil into the middle of the cup.
  6. Use scissors to make slits from the middle of the cup to the inside edge of the cup. Tape the foil to the inside of the cup. (see photo)
  7. Now make your volcano erupt! (see below)

How to 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!
