If I had a teacher like this teaching me chemistry I probably wouldn't have slept as well as I did. This teacher uses the universal theme of pumpkin carving on Halloween and combines it with every kids favorite thing, explosives! This is a really neat demonstration and I bet the kids that were in the class will remember the lesson for many Halloweens to come. Here's to creative teachers who keep the passion for knowledge alive even though school boards and tax payers seem to be pulling against them.
