Volcano

A fun and instructive project for adults and kids alike is a baking soda volcano. Take a tall glass or empty soda bottle and build a large construction paper cone around it, centering the opening of the cone over the opening of the bottle. Place one cup of baking soda in the glass (or bottle) along with a quarter cup of dishwashing detergent and a few drops of red food coloring (to resemble lava). Pour two cups of vinegar into the bottle, and watch the chemical “eruption.”
