Why can you get the bends?

Description : Why can you get the bends?

Last Answer : The reason you get the bends is because of the nitrogen inside the tank. When you are deep under water the pressure gets higher. If you stay at 20ft for 5 minutes this will release all the nitrogen ... top the nitrogen spews out too quickly which is bad so, when that happens you will get the bends.
