As the legal representative of Ad Reinhardt's estate I must insist you cease and desist or consequences will occur.
There is no reason to assume there was air in the jar before the pump sucked it out - if indeed that is what the pump did. We can’t assume the pressure gauge is functioning correctly, or even if the pump is plugged in, so it may have done...nothing. There may have already been nothing in the jar. Conversely, there still may be renegade molecules of matter in the jar even if the pump created an atmospheric vacuum.Duane Reese wrote:
You see this here?
This is a bell jar hooked to a vacuum pump.
The job of this apparatus is to create a vacuum in the jar.
The pump obviously sucks all the air out.
What do you see left in the jar?
Do you see anything?
Without the pump, you'd assume there's air, but now you know that there's no air in there either.
So what are you left with?
I rest my case. 😎🚬

This photo proves nothing.
