What You Need: 

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

What To Do: 

Attach the paper cup to the plate by taping the bottom of the cup to the middle of the plate.
Tear off a piece of foil large enough to completely cover the cup and plate.
Place the foil over the cup and plate and turn the foil under the plate edge.
Tape the foil in place.
Poke a hole through the foil into the middle of the cup.
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)
Now make your volcano erupt! (see below)

To Make Your Volcano Erupt:

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