So tonight I was sick and tired of homework and my mind was drifting while I was sitting in my dorm room. I thought to myself that it'd be interesting to look into people's dorm room from the outside through peepholes. Just simple physics of reversing light refraction. Borrowed a pair of binoculars, turned them around, put the opposite end to the peephole and to my surprise it worked! You can't see much in the room but its still pretty cool. Dare you to try it out.
