Homemade made submarine dive to depth of 100 m

I do not know whether a submarine is such an easy way to make it, but again, a man who made a submarine has appeared again. Moreover, the submarine is surprising because it is said to be a substitute for a depth of 100 m.

Details are as follows.

The submarine "2Dive" is a small submarine of two people. Michael Henrik Schmelter made it.

At the port of Kiel.

It's not that big.

Sailing in the water.

When there is an emergency, use an oxygen cylinder.
