How to make an erupting volcano at home

One of the most spectacular things you can build in your home is a volcano. It may seem impossible but anybody can make a volcano with a little time and the right materials. Making a volcano at home can be done in many different ways depending on the density or consistency you want to give the lava, the material used in the construction of the slopes and according to the virulence of the eruption, etc., all these being your choices.

You'll need:

  • Water
  • Liquid soap.
  • Paprika
  • Sodium bicarbonate
  • Vinegar
  • Used Plastic bottle

Steps to follow:


We will place the plastic bottle in the centre and make the lateral slopes with mud or papier mache. Here we will use a 1/3 litre bottle to make the volcano, but you can build a larger home made volcano using larger bottles.


You can varnish the homemade volcano with plasticine, clay or papier mache, so that the building material used is waterproof to the aqueous solution, which is the lava. This means that it can also be washed with water and thus can be used repeatedly, as if it were always the first time.


We will put two tablespoons of baking soda in the 1/3 litre bottle we selected to make the homemade volcano.


To make the volcano lava add liquid soap, about one tablespoon. You can also use water and flour to achieve the desired viscosity for the volcano lava.


Add a little paprika to give the lava volcano reddish tone. If the soap used is red this step is unnecessary.


You are now ready to erupt the homemade volcano. Just mix the ingredients with a spoon or other item, add a splash of vinegar to the mix and move back.


Now you can amaze your friends with the easily home made erupting volcano.

  • Put a sheet of plastic under the volcano so the lava does not mess up the room.
