[chbot] High Vacuum stuff

[Mark Atherton]

"Low vacuum is around 10^-4 times the atmosphere. High vacuum is 10^-8 
atmospheres. There is even Ultra-High vacuum that is around 10^-12 
atmospheres. So when you say something has higher vacuum, it’s the same 
as saying that there is less air 
inside"https://van.physics.illinois.edu/qa/listing.php?id=2238&t=high-and-low-vacuum

Pulling a large volume one.

However the phrase "continuous supply of lots of suck" seems a little 
odd syntactically since you are supplying a whole-lot-of-nothing, and 
lots of it... I need to add a smily face here, since I really can't be 
bothered with the details.

Just sayin :)
