I'm trying to make Dalek Fire Extinguisher or Cryo Gun in the party biz, for cheap.
I don't have the money to find a CO2 fire extinguisher or one of those big CO2 tanks.
So I'm going with the next best thing. A paintball tank.
I know alot of you are saying paintball tanks don't work that way, true, but they can be modifide with a dip tube or just turned upside down.


I made a video of my first test to see if it's possible & what type of CO2 containers, tanks, cartridges, will work. I don't have all my tanks & cartridges filled at the moment, but I do have a 1/4 tank filled, or 1/3 with liquid CO2. Quick test to get my hopes fired up.
Cross your fingers, or tenticals if your a Dalek. Hope this works.


In the build manual, the movie Dalek guns didn't have spacer rings on the front & back of the gun. The guns ribs were welded on to a section of metal pipe. I did the best I could with 1" PVC & hanger wire. I made sure the holes were a tight fit to the hanger wire when I glued them.

This is the measurement of the entire pipe, from the tip of the barrel to the back where the cap & air gun is attached.

When I glued the Christmas ornament half's together, I forgot to air out the ball.

TIP; When drilling the hole, DO NOT drill all the way to the full inch. The pipe was slightly smaller than the drill hole & wasn't a tight fit. I drilled the second hole one space down & Dremaled the rest to a tight fit.

All I need now is a bottle of CO2.
