How do submarines work?
When the ballast tanks are filled with air, the submarine rises to the surface because it has positive buoyancy. With water inside the tanks, the sub has negative buoyancy so it sinks deeper into the ocean. The ballast tanks can also be used to help a submarine surface very quickly in an emergency.
Who built the first submarine?

How deep in water can a human go?
In short: most of the body can handle any pressure, but if we’re breathing air the maximum safe depth is about 60 meters (190 feet), the feasible maximum with current technical capabilities (and special breathing gases) is about 500 meters (but, for safety reasons, those depths have only been simulated).
Can divers go down to the Titanic?
No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure.
How deep can you dive before being crushed?
How Deep Can a Human Dive Before Being Crushed? There is no fixed depth where we can say for sure that a diver will be crushed once they cross a certain depth. Most recreational divers don’t generally go beyond 130 feet, but commercial divers manage to reach depths of 2,000 feet with the help of atmospheric suits.
Is diving good exercise?
Diving is therefore not only a good workout for healthy individuals, but also a great form of physical therapy for those recovering from injury. Some scientists even believe that scuba may decrease the time it takes for wounds to heal, thanks to the body’s consumption of concentrated levels of oxygen at depth.
What should I eat after scuba diving?
Eat plenty of high-carb foods after your dive and every couple hours after. You may not dive any deeper or longer but eating healthy may make the difference in how you feel during and after your spectacular diving adventures.
Can you talk while diving?
Scuba divers are trained to use hand signals to communicate with their buddies. They also use underwater writing boards, which allow for better communication. The same system can be used for communication between the diver and a surface ship. Acoustic communication systems allow divers to talk to each other underwater.
Can you drink water underwater?
Sea Water isn’t potable and should under no circumstances be consumed, given its salt content… so when scuba divers go diving, it’s a good idea to have access to drinking water.

What is there underwater?
The underwater environment refers to the region below the surface of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Liquid water has been present on Earth for most of the history of the planet.
What is a deep underwater canyon called?
