Homemade Submarine.

This impressive underwater vehicle was built by Russian man from St. Petersburg. It is officially registered as a boat by Russian boat registry & has its own personal name & number. Another impressive thing about this one man, home-made submarine is it made an underwater trip from St-Petersburg to Helsinki & back, without having to make any stops. This submarine reaches a top-speed of four knots.
