How do you make a volcano?

Answer 1

To make a volcano, the following steps are to be followed :

1. The first step is to sculpt your volcano out of the sand. Take special care to hollow out the inside of the volcano so that you can place the plastic cup inside. The easiest way to do this is with a spray bottle of water. Take the time to carve ridges into the volcano for effect.

2. Once you have the volcano sculpted, add the baking soda to the cup, being careful to not disturb the structure. At this point add 3 or 4 drops of red food colouring to create the look of the lava.

3. When you are ready for the volcano to erupt, add in a 1/4 cup of vinegar to the mix. It is an impressive effect!

4. Once the lava is flowing, be sure to create ditches for the lava to travel through. It really adds to the effect.

*You can build a volcano with sand or clay or some kind of mold. Your choices are not limited, so be creative!!!!

Things You'll Need:

• Sandbox (or sand and a flat board)
• Baking soda (tablespoon)
• Red Food Colouring
• Vinegar
• Any accessories to add effects (trees, bushes and rocks)
• Plastic cup or a bottle

You cannot make/fabricate a natural volcano.
