How to Make a Paper Mache Volcano

Kids crafts with paper mache ideas are so much fun. Like this super cool erupting paper mache volcano project. It’s easy to make at home, so let’s get started:

You’ll need:

  • cardboard (square 2x2 feet)
  • an empty small soda bottle (no lid)
  • masking tape
  • newspaper and paint
  • paper mache paste (made from flour and water) or PVA glue (watered down)

You can use watered-down white PVA glue, or make your own paper mache paste from flour and water: Mix 3 parts water to one part flour. Making paper mache can be very messy, so before you start, be sure to protect all your work surfaces and clothes.

To make:

  1. Place soda bottle in a centre of the cardboard and hold together with masking tape.
  2. Use cardboard strips to shape the volcano by taping one end to the bottle top and the other to the cardboard base.
  3. Overlap strips to form a sturdy base.
  4. Leave the bottle opening uncovered. Tear newspaper into small pieces, dip into paper mache paste or PVA glue mixture and stick it all over the shape. Repeat until it’s all covered.
  5. Apply 2-3 layers until you get the volcano shape you like. Let it dry for 24 hours. Then paint the volcano as you like.

To make your homemade volcano erupt:

  1. Place outdoors on a sturdy surface.
  2. Gather your supplies: 1 tablespoon warm water; liquid dishwashing detergent; red food colouring; 1 TBSP baking soda; vinegar and a small paper cup.
  3. Mix water, dishwashing liquid and red food colouring.
  4. Pour into the top of the volcano.
  5. Add baking soda and stir with a narrow stick.
  6. Fill a paper cup with vinegar about 1/3 full.
  7. Then pour into the crater, step back and watch your homemade volcano erupt!
