13-year-old supernerd Hibiki Kono designed a wall-scaling device using two Tesco Value vacuum cleaners he purchased for £14.98 each.

“My mum thinks it’s brilliant but she won’t let me us it in my bedroom as she is worried I may pull down the ceiling,” Hibiki was quoted as saying. “I used to dress up as Spiderman when I was younger and I love all the films so it’s great to be able to climb walls like him.”
