I’m organizing some photos tonight and found this one, which struck me as funny for some reason.

I’m explaining how a rocket works to my second-grade science class. Notice the hydrogen and oxygen tanks (not entirely accurate, but oh well– these are second graders). Also notice the little astronaut standing in the capsule at the top of the rocket.

They were completely enthralled; I’m not sure if it’s because they were really interested in rocket propulsion, or because they were waiting for me to get to the part about the Diet Coke and Mentos.
