Ok here's what you do. You take your finger and go into a bathroom. You write with multiple fingers the message you want to show on the mirror. If the miror you use is blocked when your victem takes a shower than it won't work. What it does is when the victem takes a shower the miror fogges up except where you smeared your fingers on the mear rubbing oil onto the mirror. Basically when your victim takes a shower you do it on a mirror that gets fogged up. So when he gets out of the shower it is like a ghost wrote on the mirror. Alst. cool huh
