So enraptured of Spider-Man was 13-year-old Kono that he constructed a device that allows him to scale walls by crawling up them. Entirely on his own, he spent five months working on a gadget that connects two vacuum cleaners to a pair of “giant suckerpads,” which uses tremendous suction power to allow him to cling to walls. It appears to work on walls of all kinds, even brick.
The only caveat for the machine’s use is that it’s powered by a regular electrical cord plugged into a wall outlet, so it can only go as high as the cord will allow. But Kono used his machine to climb a wall at his school’s assembly, as a proof of concept, and it was a big hit, impressing his teachers and headmaster. But his mother won’t let him climb the walls at home, out of fear that his powerful gadget might “pull down the ceiling.”
Kid can crawl up walls at 13. Maybe by 20 he can find a way to make a man fly.
