The document provides instructions for making a baking soda volcano. It explains that the volcano eruption is the result of a chemical reaction between baking soda and vinegar that produces carbon dioxide gas. As the gas builds up pressure inside the plastic bottle, it causes bubbles (thanks to detergent) and the "lava" to erupt from the opening. Food coloring can be added to make the lava appear red-orange.

1. The Soda Volcano
The baking soda volcano is the kitchen equivalent of a volcano, not a real one. It's cool all the same! The baking soda volcano is also
more or less non-toxic, which adds to its appeal.
By the end of the experiment you'll be surprised from the volcano eruption. Here are some tips explaining what happens:
-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.
