This was something dumb my brother did. He wanted to get extra steps for his pokewalker, so he ducktaped it to a little fan (not the ones that hang from ceilings) and turned the fan on. He left for like 3 hours, came back, and the ducktaped was smoking and some near papers had caught on fire. Luckily, his pokewalker was fine, but it was a little charred.
