My favorite Leonardo Da Vinci inventions
The Diving Suite
The Diving suite was designed by Leonardo Da Vinci so that people could originally go underwater for long periods of time and savatage other enemy ship by cutting holes or gaps in their underbellies. There were a few versions of the suites. In one version the person would be inside the suite with a air tube in which they would breath from. In the other version the person would have wine bladders which would be filled with air and hopefully last a while. One of the major flaws Da Vinci had with these was that while they could breath for long amounts of time, they would also have to hold it for long amounts time. So when designing them he had equipped them with a bottle to urinate instead of having to get out of the water.
