Step 1: Collect tools and ingredients The project requires a number of ingredients, most of which are readily available at home.

  • Aluminum sheet
  • Cardboard box
  • Old newspaper
  • Tray with raised sides
  • Flour
  • Salt
  • Small plastic bottle
  • Funnel
  • Measuring spoon and cup
  • 3-4 tablespoons of baking soda
  • 1/2 cup of vinegar
  • Dish washing detergent
  • Red food coloring

Step 2: Prepare work area Cover the work area with newspapers. Cut a large cardboard piece and fit it into the tray to form the volcano's platform. The tray's raised edges help contain the eruption.

Step 3: Set up the eruption Cut the top of the small plastic bottle at an angle and glue it to the center of the cardboard sheet. Add the vinegar, a few drops of dish washing detergent and red dye to the bottle.

Step 4: Build the volcano Make modeling clay by adding water to a mixture of flour and salt till a clay-like consistency is achieved. Build the volcano from the bottom by molding the clay around the base and working in narrower sections towards the top. Allow the clay to dry for a while and sculpt gullies and channels for a more realistic appearance.

Step 5: Paint the volcano When completely dry, paint the volcano in different colors to simulate rock, trees and snow.

Step 6: Erupt the volcano Once the paint is dry, the volcano is ready. Place baking soda in a small piece of tissue, gather the edges and twist them closed. Drop the package into the volcano. It should erupt in a few seconds. The volcano is durable enough to reuse several times.
