Regular Joe builds submarine for $4,385 in China

34-year-old Tao Xiangli is an amateur inventor whose efforts aren't looking all that amateur. The Chinese man has built himself his very own sub all on his own, spending two years and 30,000 yuan ($4,385) on the project. It's driven by electric motors and propellers, and even has some extra fixings, including a periscope and a depth control tank. And, unlike this Chinese-made helicopter, it looks like he's being allowed to take it for a spin.
