Microwave Patent
National Microwave Oven Day is today! The history of why this day was chosen to celebrate microwave ovens is obscure; the micowave oven patent was awarded on October 8, 1945, to Percy Spencer. However, most people now depend on their microwave ovens on a daily basis. Idea: Children could record how many times a day people use the microwave and why. They could figure out what patterns become obvious.
