Volcano

We did our volcano experiment!  We were supposed to build a "mountain" of dirt around the water bottle, but the dirt in our backyard is as hard as stone right now.  And I wasn’t in the mood to deal with mud, so we just stuck the bottle in some clover to hold it up!  Inside the water bottle was 2 T. of baking soda, a few drops of dish soap, and a few drops of red food coloring.  After it was all in place, I poured some vinegar in it, and it erupted!
