Do you need to make a model of a volcano for school or a science project, or do you just want to do this for fun? Well this is an easy and inexpensive project. Just look below to create an amazing volcano.

To step

Part 1 of 2: Making the clay

1. Collect your ingredients for the volcano in the kitchen. You will be making simple clay that looks a bit like Play-Doh. You need the following:
   • 750 grams of flour
   • 500 ml of water
   • 4 tablespoons of vegetable oil
   • 400 grams of salt
   • Old plastic water bottle, cut in half
   • Food coloring (optional)
2. Let the dough dry for 1-2 hours before modeling with it. The clay should be wet enough to work with, but not so dry that the material crumbles and falls apart. You can always add a little extra water if needed, but not too much.

Part 2 of 2: Making the volcano

1. Let the volcano dry overnight, or bake it in the oven for an hour at a temperature of 110 ° C. First mold the volcano and let the clay harden. Since this is actually play clay and not real clay, let the volcano dry and harden for about 24 hours before finishing your project. If you're in a hurry, put the volcano in the oven on a low setting for about an hour to let it dry faster.
   • Don't forget to paint the volcano when you're done.
2. Run away! The toilet paper will dissolve, exposing the baking soda to the vinegar. This will cause the volcano to erupt.

Tips

• Make sure no one else has the same idea as you.
• You can also research the different volcano shapes and choose your favorite volcano shape.
• Another way to make a volcano is to fold a piece of cardboard into a cone and cover the cone with clay.
• Read this article for even more methods of modeling a volcano.
• Vinegar can be very smelly, so throw away the newspaper and wipe it up with a paper towel. Rinse your volcano for next time.
• Let the volcano erupt outside in your garden. You can also put this in a small box. It produces less mess and it is easier to clean everything outside.
• You can paint the volcano as a peaceful mountain with trees and snow. The volcano then looks more like the volcanoes in the American states of Washington, Oregon and Alaska.

Warnings

• Wash your hands with warm water and soap afterwards.
• You will make a lot of mess on this project. It is a good idea to perform these steps outdoors.
