Does not pull a full vacuum for penny-and-feather physics demos or the "bell in a jar" demo. The low pressure it creates DOES make a difference in the bell volume and the time it takes a feather to fall, but it doesn't get the air pressure low enough for the feather to fall at the same rate as the penny.

Yes, I recommend
I'm excited to try it even as a vaccum pump and as a compressor to dry glass tube!!!
It's a 2 in 1 product that seem to be very convenient.
Thanks a lot for your suggestion.
