Thirteen-year-old Hibiki Kono, who lives in the U.K., made an awesome wall-climbing machine using two 1400-watt vacuum cleaners. He spent five months working on it during design technology classes at his school. His only obstacle? His mother. “My mum thinks it’s brilliant,” he said, “but she won’t let me use it in my bedroom as she is worried I may pull down the ceiling.” Video at TheDailyWh.at.
