Video Description

This video will show how to make a vacuum pump, a device that can be used to suck the air out of sealed environments. This is the same pump I use to operate my vacuum cannon seen here: http://youtu.be/CVL99yIB3NQ A clear vacuum chamber such as the one seen in the video can be obtained by purchasing a bell jar and vacuum plate, easily available online. I highly advise that only vessels made for handling vacuum pressure such as bell jars be used with this or any vacuum pump. If a vessel were to fail while under vacuum the implosion can be powerful enough to cause injury. See this video for an improved piston design that can be used in this pump: https://youtu.be/5SBSN7wFx4A?t=2m8s Vacuum Pump Parts: 16" of 2" PVC Pipe 20" of 1 1/4" PVC Pipe 2" End Cap 1/4"x1/8" Brass Hose Fitting 3' of 1/4" Vacuum Line 1 1/4" End Cap (x2) 1 1/4" Diameter O Ring 2" Coupling 2" x 1 1/2" Reducer 3" x 2" Adapter 3" x 4" Closet Flange 4" of 3" PVC Pipe 10" of 3/4" Dowel Self Tapping Screws Bearing Grease 1/8" Sheet Rubber And/Or 1/16" Sheet Rubber
