[PSUBS-MAILIST] Dive report: Snoopy at Seneca

[Alan via Personal_Submersibles]

Just correcting myself. I said it would only take less than a psi
to squeeze the existing tube, but would it??? Yes if you just squeezed
it from side to side with your fingers, but If the water is squeezing evenly 
around the tube, perhaps it would take a lot of psi to get any crushing 
of the tube that would cause equalisation. 
Would be a good pressure chamber experiment.
