Bell Jar or Peeps in Space

Made a vacuum pump out of PVC and a Bell Jar out of Acrylic. Then I thought what would a peep look like in space?

Description

This was a fun lathe and mill project to make a manual vacuum pump and bell jar. The pump has a check valve in the end and a flapper valve on the piston end. There is very little dead volume in the pump so that can achieve 28 inches of Hg in a very short time.
