HOW TO MAKE A VOLCANO

Tips:

•  The cool red lava is the result of a chemical reaction between the baking soda and vinegar.
• In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.
• As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until the gas bubbles (thanks to the detergent) out of the 'volcano'.Adding a bit of food coloring will result in red-orange lava! Orange seems to work the best. Add some red, yellow, and even purple, for a bright display.
