There's no need for anyone to run for cover from this safe model of a real erupting volcano.

What You'll Need:

  • Tall jar with lid
  • Water
  • Baking soda
  • Dishwashing liquid
  • Red or orange food coloring
  • Large plastic container or wash basin
  • Dirt or plaster of Paris and paints
  • Pine cones (optional)
  • Vinegar

How to Create an Erupting Volcano:

Step 1: Have your children find a tall, thin jar -- the kind of jar that pickles or olives come in works well. In the jar, have your kids mix together 1/4 cup water, 1/4 cup baking soda, three tablespoons dishwashing liquid, and a few drops of red or orange food coloring.

Step 2: Ask your kids to place the lid on the jar, and set the jar in the center of a big container.

Step 3: Your children should then build a "mountain" of dirt or sand around the jar. (It will work better if the dirt or sand is slightly wet.) If they'd like, they can cover the mountain with plaster of Paris, and paint it to look like a real volcano. They can even decorate it with pine cones to look like trees.

Step 4: Now ... it's lava time! Have your children take the lid off the jar, quickly pour in 1/4 cup of vinegar, and stand back. Everyone can watch the volcano erupt.
