The students get to tear the products apart, test the components, figure out how they work and then build stuff back however they want to. This is good. It teaches students at a a prime age that the little metallic warning sticker on the back of the VCR is just a suggestion, not a mandate. Unfortunately, we aren't allowed to show the faces of these future tech overlords of America in these pictures because the Internet is occasioned by Boggarts and Vermicious Knids, but trust us - they look as smart as they are.
Have fun kids. And remember what ThinkGeek taught ya, 'It doesn't matter if it's broke or not broke, just take it apart and fix it anyway...'
