Homemade Volcano

Okay, so everyone's seen this one before, but sierra had to make a volcano for school so we documented it.
1 pop bottle (ours was a 3 liter)
depending on the size of your bottle you will need 1 to 2 cups of vinegar
also depending on the size of your bottle, you will need about 1/4 cup of baking soda.
a few drops of red food coloring (unless you want a unique volcano with some green or blue)
(use more or less if needed)

We started with the baking soda in our bottle and in a cup mixed the food coloring and vinegar. Then we quickly poured them into the bottle (already full of baking soda) and stood back.
It was so fun that we did it a few times. This is especially fun with younger kids who have never seen this before. the end result, a bubbly volcano. when i was younger we put toy dinosaurs around the bottom of the bottle and pretended it was a prehistoric eruption. Be creative and have fun with it.
