Erm, isnt this more of physics and maths than biology?

SO yea, it can stand 127 N of weight. If water has a weight of 10N per 10 metres (I have forgotten the actual data, read it a long time ago, it had something to do with a thermometer that some guy made), then it can go about 12 metres down. 

^^ I am not sure. Ask the physics guys.
