Chinese dude builds a fully functional sub

for some reason i would not want to go in this thing.
"Tao Xiangli, a Chinese inventor, is reported to have built a functional submarine:

Amateur inventor Tao, 34, made a fully functional submarine, which has a periscope, depth control tanks, electric motors, manometer, and two propellers, from old oil barrels and tools which he bought at a second-hand market. He took 2 years to invent and test the submarine which costs 30,000 yuan (US$4,385)."
