A 13-year-old schoolboy has managed to climb walls using an invention he created for a class project.
Hibiki Kono, along with his teacher Angus Gent, explained to Bill Turnbull and Sian Williams how it works and the inspiration behind the idea.
Hibiki was inspired by the BBC's Bang Goes the Theory. You can find out more at bbc.co.uk/bang
