The team has wisely opted to ditch charges made of gunpowder, in lieu of a design where individual pieces of the wooden chair that are held together will rely on wax joints that have been fitted with nichrome wire. There is an Arduino-based mechanism that is connected to a contact switch which will know just how many times someone has planted his or her rear end on it, knocking on the wood each time they get up, to show just how many times left you can seat on the DRM Chair. After 8 sits, the self-destruct system will kick in, where the wire heats up until all joints have melted, turning it into a worthless piece of furniture. Sure heck of a way to get your message across, no?
