I guess it would help but I don't know of many vacuum pumps that can suck more than one negative atmosphere - that's about 14 PSI (and pretty good going) - is that enough to break the bead? I don't know - it could be - it might not - like I said you need some good lungs!

As a point of interest our (OM617) vacuum pumps are meant to be good at 10-15mm hg (right?) that's about 0.2 PSI if I've got my conversions correct.

Atmosphere (unit) - Wikipedia, the free encyclopedia
