Hot Dog Solar Cooker

Yesterday, I started my new class for grad school, Operation Physics. It is all day, M-TH of this week and M-F all of next week and three Saturdays this fall. We do a different unit everyday. Today's topic was heat and temperature. I had to take in a pringles can. The Pringles can was turned into a solar cooker, and we cooked hotdogs for lunch. The temp outside wasn't very hot, so the hotdogs didn't get very hot. We called the shrubs covered with our hotdog cookers, hotdog trees.
