Magnum Toilet Paper Cannon

My Air Cannons Magnum Toilet Paper Cannon

Suddenly it was snowing endless white streamers, but then I realized that the guy more than a block away had just shot off his Magnum Toilet Paper Cannon. 

The art of toilet paper decorating is making a comeback. Whether at a parade or simply enjoying some "recreational throwing" you will be able to surprise everyone with this baby! 

There are a lot of reasons for owning one of these cannons. It is truly a lot of fun to shoot streaming white rolls of paper over so many things. The surprised looks on peoples faces when the gentle streamers of white slowly descends over them or just the fact that you can use this magnum cannon for a multitude of tasks in addition to toilet paper. 


1) Toilet Paper (5 rolls at a time if you like) 

2) Stuffed Animals 

3) T-Shirts, including unwanted laundry (yes even panties!!!) 

4) Confetti, on mass!!! 

) Water - Be careful with shooting water as it is more equivalent to a fire hose. 

6) YOU HAVEN'T LIVED until you have shot off a barrel of popped popcorn. Instantly turn a room white - Maybe at the office. 

For those of you who want technical information I am offering a quick design snapshot (for those of you who are working on related air driven systems or who are just plain curious). 

This entire Toilet Paper Cannon is made with high pressure schedule 40 (or better) PVC components. 

A lot of research went into making this (indispensable) Toilet Paper Cannon. There were a lot of adjustments from the theoretical to the practical. I had considered using a standard 4" over/under configuration, but the safety head space and the expansion characteristics were poor at best. These are only a few of the reasons I chose the twin 2 1/2" firing chambers. You get a much steadier "push" with less jerk from the twin cylinders as well as a better feed in the mixing chamber ahead of the release valve. Smoke tests and measured pressure graduates on the barrel proved the 2 1/2" tubes to be the best "in the real world". Not to mention the circular mil constant of 4" was 12.57 (rounded), where as the constant for the 2 1/2" are 15.71. The calculated optimal length for the barrel was 27.3". After a battery of test, a shorter length was decided on. The width of the barrel end itself is 4" which enable you to launch a vast array of items. 

For you military buffs, a 4" barrel = 101.6mm, and you thought the Germans' 88mm guns were something! 

The possibilities are limitless! 

It is intended for entertainment for adults and amazed bystanders. 

This is a great cannon, incredibly fun, a blast to use and a real attention getter. It operates on air pressure alone so no flammable or dangerous accelerant's are required. There is also an air pressure gauge installed on the back of the cannon which makes repeatable, predictable shots easy. If the kids with super soakers see you operate this with water they will throw their water guns away and want yours. Use it once and you will wonder how you lived without it. Truly one of the more enjoyable experiences in life. 


Watch it in Action!

Now you too can build the Magnum Fired Toilet Paper Cannon and these plans will tell you step by step how.
