We made… probably the craziest thing we’ve ever done. We built a propane cannon!!!
Who hasn’t watched Mythbusters and wanted to make something blow up and then watch it in slow motion? We made this see though propane gun to do just that.
This was quite an experiment for us both in terms of the build and by getting into “science” like content. Instead of building a typical potato/spud gun we used propane as the fuel, which let us fire faster… once we figured out how to get it to fire…
This was inspired by three other channels: NightHawkInLight (https://goo.gl/rnWuSW), TheBackYardScientist (https://goo.gl/b1YHvi), and SmarterEveryDay (https://goo.gl/n7hY4e)

NOTE: We cannot recommend doing this. We have background and experience that allows us to take this on safely. A propane combustion should only produce 40-50 PSI at atmospheric pressure with normal atmospheric oxygen levels. To be safe we used Schedule 80 pipe with a minimum pressure rating of 140 PSI for all connections. If you make something like this despite our warning, PPE should be worn at all times (ear and eye protection).
