Make a salt volcano

If you are preparing a science project on volcanoes, you may think you need to build an explosive mound of mass and clay.

However, this type of volcano project is very common, and does not seem original as a science experiment.

An alternative is to make a salt volcano, which shows how a volcano works without using the standard materials that would be used in a mud or paste volcano.

You'll need it:

  • 6 cups flour
  • 2 cups salt, 1 tablespoon baking soda
  • 4 tablespoons cooking oil
  • 2 cups water
  • Food coloring (the color of your choice)
  • A cardboard box, newspapers
  • An empty bottle of soda
  • Glue
  • 1 tablespoon dish soap
  • ΒΌ cup white vinegar

Steps to follow:

1 Mix 2 cups flour, 2 cups salt, 4 tablespoons oil and 2 cups water in a bowl. Stir ingredients with hands until combination forms a consistent paste.

2 Put a few drops of food coloring in the mixture, preferably brown or red to achieve the exterior color of a real volcano. Put the dough aside.

3 Place a piece of cardboard on a table. Stick a bottle of soda in the center of the carton.

4 With the beak up (stop) Arms small balls with newspaper and place them around the bottle, gluing them together to form the base, and accumulate at the tip of the volcano forming a cone.

5 Stir the dough again and place it on top of the newspaper balls and bottle to form the outer shell of your volcano. Carefully and gently mold the dough. Make a hole in the center of the dough to expose the peak of the soda bottle.

6 Now you have to paint the mass of the volcano to make it more real. You can use images of volcanoes to guide you, or make a design you like. When you're done painting it, let it dry for a full day.

7 Add 1 tablespoon of dish soap and 1 tablespoon of baking soda to the bottle, along with a little red vegetable dye and 1 cup of water. When you're ready to see the lava explode, add the vinegar to the bottle and quickly step back waiting for the results.
