Candle Cannon Answered

These guys built a huge version of the AirZooka and are able to send blasts of air strong enough to knock out candles at well over 100 feet.

I want to make one!

Great vid, though I'm curious what easy to generate smoke do you make assuming you aren't a rabid chain smoker or playing with oily rags?

You can buy theatrical smoke generators (which is what they seem to be using in the video), or plant a load of incense sticks inside the beast.

I've heard of people filling air cannon with smells - apparently the chap that invented them made one the size of a barrel, then shot people with invisible stinks in the street - they would suddenly find themselves in a cloud of odour.

I have also heard plans to fill air cannons with flammable vapour and shoot them at ignition sources - shoot a cloud of alcohol vapour at a smoker and they get enveloped in a momentary flash of flame.

I loaded an airzooka with cigarette smoke back in the day when I had a friend who smoked- the rings were a lot more impressive of you just fired it gently. We did plan to add butane injection to it as we were already working on a remote butane system for his go-ped but never got round to it. I believe the original inventor fired hydrogen sulphide at people in the street... ewww.

It would be bad if it ignited inside the barrel :(

Think of the smoke ring it would fire, though...

Speaking of speed and smelss this somehow reminded me of part of Ron White's standup routine where he said something like:

We were traveling by plane at half the speed of smell and got passed by a kite. Then one of the two engines failed. And the guy sitting next to me went nuts and asked how far the other engine would take us, and I replied, "All the way to the scene of the crash, bet we beat the paramedics there by a good 35 minutes....

Airzookas are so much fun - we have two, and #1 son and I have frequent gunfights with them.

I built one last year with my Science Club, using a large cardboard box, but it ha since been recycled. I really must replace it...

what material/cloth did you use for the part that pushes the air?

Select as Best AnswerUndo Best Answer

Just a plastic bin-bag, cut and opened into a sheet.

The box was about 3x3 feet* on the end, and about 4 feet long. I didn't use bungees, but I added a cardboard handle on a cardboard disc to the centre of the bag to allow for easy pushing.

The hole I cut in the front of the box was about 8 inches diameter. It could knock Christmas cards over at a range of about 5 or 6 yards. If I had bothered to taper the body of the cannon, and used a cylindrical body instead of square (like in the video), it would have had a much greater range.
