Is it a plane? No, it's a… flying bathtub

Two curious inventors have left other drone pilots running around in circles by creating their own human-sized flying machine using none other than a bathtub.

The eye-opening footage of "the world's first manned flying tub" shows how Johannes and Phillip Mickenbecker managed to successfully get their creation off the ground, flying it around a local gym with a pilot inside in Germany.

Remote-controlled, the flying machine is a concept that Di Vinci himself would have been proud of, using drone technology but on a much larger scale.

The brothers - who call themselves The Real Life Guys - searched for special propellers that could make the bathtub fly in a stable manner around two months, and once the propellers had been sourced, the brothers teamed up with friends at a company, who helped them with the flight controls and programming.
