Kid Makes Spiderman Machine, Scales Wall

The 2002 installment of Spider-Man cost $140 million to film—but one intrepid 13-year-old has figured out how to scale buildings for a whole lot less. Hibiki Kono devised a wall-climbing machine out of two $22.50 vacuums, reports the Sun. The British boy spent five months toiling away at the design, which fuses two large suckerpads to the 1,400-watt vacuums. "My mum thinks it's brilliant," says Kono. "But she won't let me use it in my bedroom as she's worried I may pull down the ceiling." (More Spiderman stories.)
