The Taylor 550 Projector Scale is a useful gadget that could also be very embarrassing. See, it projects your weight onto the wall so that you don’t need to look down for whatever reason — if you’re older, or if you can’t see around your bulging stomach. It’s got a max weight of 550 pounds and runs on AA batteries. Personally, I think it could be used as a great (and mean) prank to play on someone at a party…if you’re into that sort of thing. It’s available now for $63.
