As the reporter from Mail Online, where I first ran across this news, says, this new, little, pedal-powered yellow submarine looks like something out of a James Bond film. It also makes me think of those big water bicycles you can pay $10 or something to use on touristy beaches (i.e. in Florida, where I grew up).
This yellow pedal-powered submarine is nicknamed “the Scubster.” The propellers on the sides that make the submarine go are connected to a pedal belt. The submarine can reportedly go “8km an hour (5mph) if its pilot is in good shape, and can reach depths of 6 metres (20 ft).”
