There is a device called a rebreather that can be used by Scuba divers. Under normal breathing no bubbles are emitted from a closed loop rebreather. Rebreathers work by allowing the diver to breathe out into a bag called a counter-lung. This can then be breathed in again. If you tried this at home with a bag, you would quickly pass out because you would either use up the oxygen in the bag or get poisoned by the carbon dioxide level increasing. To stop this, rebreathers have chemical scrubbers to remove carbon dioxide and inject a bit of oxygen every now and again. The way that oxygen is added depends on the type of rebreather and model. When coming from depth to shallower water, all rebreathers need to give off excess gas as the pressure reduces and the gas expands. Not having bubbles is handy for covert diving but is also useful for underwater Photography and video work as they are quieter and don't scare off the marine wild life so much.

Its water the bubbles because water is a liquid it obviously wont wont hurt you but divers when they hit the water hard the hurt themselves so a lot of water can be strong sometimes so its the water that pushes the beans down
Why does your scuba tank not get crushed if it is empty?
a scuba tank is very thick, and so it wont be used if empty the valve remains to be closed, not allowing any air to excape, disallowing to be crushed. if the air cant leave the tank it wont crush.

Can you die from scuba diving and then flying?
So far as I am aware, there are no recorded instances of anyone dying as a result of flying after scuba diving. However, it is widely recognised that flying creates in increased risk of decompression sickness, and there are plenty of divers who have suffered minor DCS incidents on aeroplanes. This is why divers are always recommended to wait at least 12 (and preferably 24) hours after finishing a dive before they fly.
