One of my favorite YouTube school related videos was done by a teacher demonstrating a piece of equipment that involved burning propane and felt it was best to not bring it to school.
Most kids will swear it's faked when they watch it the first time because it's so eye-catching. It's a great video and worthy of more press than it gets.
As mentioned in Thing 9, I am capable of downloading, converting, and burning YouTube videos to DVD. It just takes a while.
