Once again, these pictures were taken in September. We're studying chemistry this year and I thought it appropriate to begin with the classic baking soda and vinegar volcano. To increase the fun, we added some red food coloring and dish soap so it would foam red.
First Daughter poured the baking soda.
First Son poured the vinegar, water, dish soap and red food coloring.

Some relaxation after a job well done:
