A university student came up with a new business idea during a night out and in six weeks has made more than $100,000 (£55,000).
Bailey Page, from Queensland, Australia, invented a new wireless phone charger after his mobile ran out of battery while he was ordering an Uber home from a nightclub.
The 22-year-old looked online for a cable-free charger that could fit in his pocket the next day but couldn't find one.
