Latex tubing will "blow up", like long skinny balloons do, zooming to a dramatically expanded size (8x initial diameter & 2.5x initial length) once a threshold pressure is reached (around 30 lbs for smaller sizes). Then it will only take a limited amount more pressure (or stress to the super taught expanded membrane) before it bursts.

Having used long pieces of it in water fights, with the latex tubing inflated with tap water & wrapped around my neck and body like a boa constrictor, I can tell you that when it does rupture, it does so with dramatic force. I felt like I had been hit by a strong karate chop. Not sure if it was the water or the rubber snapping me, but really stunned (and soaked) me.
