Russian smallest submarine

Submarine.A man from St. Petersburg, Russia, built himself a submarine – smallest in Russia.

He can make an underwater trip from St. Petersburg to Helsinki, Finland and back without stops, and he can go as fast as four knots. The interesting thing is that he is based in St. Petersburg which is in Northern part of Russia so the water in the sea is cold all year round.
