Make a High Volume Manual Vacuum Pump

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.

This pump is capable of generating pressures of 29 in/Hg.
