How to Make a Homemade Volcano for Your Science Project

Volcanoes are very interesting effects of nature, and popular choices for science projects. The effect is easy to produce and great fun for your children. Take a Saturday morning to amaze them with this great special effect! Read on to learn how.

Difficulty: Easy

Instructions

Things You'll Need:

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

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 coloring 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.

Tips & Warnings

• If sand is unavailable, you can use plaster, clay, or even dirt.
• Do not erupt your volcano in the house. It can get away from you.
• Do not over do the ingredients unless you want a huge mess.
• Take special care to monitor your children while doing this project.
