The Great Volcano Experiment

Daniel made a volcano in the backyard out of dirt and rocks about a week ago and it finally stopped raining long enough for the muddy ground to dry out when I was off work during daylight hours. I found a recipe on the internet a while back to make his volcano "erupt", so with great anticipation the kids and I trudged down stairs with the ingredients and my loaded camera. I mixed the ingredients (baking soda, dish soap and food coloring) according to directions an empty film canister and stuck it in the volcano cone then had Daniel pour the vinegar in with my camera ready. We waited. "Mom - it's not doing anything." "Just wait Daniel, it takes a minute." Again we waited. "is that it?" Then it started frothing like a rabid dog, and then - THAT WAS IT! A weeks worth of anticipation for a teaspoon of orangy froth. Not the ooze of magnificent proportions that we had all envisioned. {Sigh} Back to the drawing board.
