Make an Erupting Volcano

Make an Aluminum Foil Volcano which really Erupts!
I’ve done this science experiment with kids at least three times for school projects. It’s always a hit because kids like seeing the volcano erupt. Simple explanation for how it works: Baking soda is a base substance whereas vinegar is an acidic substance. When the two are added together it causes a reaction. In this case an erupting volcano.
To make a volcano fit for a science fair you might want to make it more life like, like painting it brown. Or making your volcano out of Paper Mache or clay. To make this basic volcano you need: Two paper cups, paper plate, aluminum foil, pen, masking tape, scissors, two tablespoons of vinegar, tablespoon of baking soda, one and half tablespoons of warm water, old cookie sheet.
This experiment should be done with an adult present.

1)Place cup side up on middle of plate. Keep it place with masking tape. Now totally cover cup and plate with aluminum foil. Tape extra foil under plate.

2)Using your pen, poke hole through aluminum foil in very middle of cup. Using scissors inside cup, cut four slits in aluminum foil from poked hole to edge of cup. Fold aluminum foil down inside cup and tape securely.

3)Place your newly made volcano on the cookie sheet. Put one tablespoon of baking soda in middle of volcano (cup). Add one and half tablespoons of warm water to this. Mix gently. In another cup put in two tablespoons of vinegar. (If you were taking this volcano to school you should carry needed vinegar amount in a small container or leave in bottle. Every time I’ve done this project kids like to see the volcano erupt over and over, so bring enough ingredients to erupt volcano at least three times.)

4)Get ready for an eruption! Pour vinegar into middle of volcano cup. Up comes the lava.
