To sink, a submarine must weigh more than the water it displaces – this is called a negative buoyancy. So to get it to weigh more, special tanks are flooded with water. This makes the sub heavier and so down she goes. And when they want to go up, they need to make the sub lighter.

What do submarines do with human waste?
Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.
Why can’t submarines go to the bottom of the ocean?
So you can see how even machines have to be incredibly tough to be able to withstand that pressure without crumpling like an old pop can. Deep sea submarines – the ones that go deeper than anything else – have to have very thick hulls. Their windows are made of super thick glass.
How long can a submarine stay underwater?
Air isn’t a problem as their make their own oxygen and keep the air clean. The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater.

Most subs have two types of sonar: active and passive. Active sonar sends out acoustic sounds, or “pings,” which can reach thousands of yards. If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine.
What happens when someone dies on a submarine?
If the submarine is in operation, they can be on board for a couple of days to several weeks, it really does depend on the situation. In a nutshell, when someone dies on board, it can become a crime scene where nothing can be touched if they are in operation and then it’s time to prioritise food.
Do submarines have toilets?
HOW DO YOU USE THE TOILET ON A SUBMARINE? Pressurised seawater is used to flush the toilets on a submarine. A simple ball valve operates the flush on the toilet which enables the toilet to be ‘plumbing free’. Once flushed, you then manually turn a valve next to the toilet to refill the bowl.
