for a science fair project i'm going to show how to build a film can cannon and explain how they work and im using stuff i foung around the garage im using a blocks of wood and all this stuff. since i couldnt find an igniter im going to use an ignition spark coil and right gard spray. will these 'substitutes' work? | ||

The spark coil will need a battery and a switch. It is really easy to find an electronic lighter at a drug store or a grocery store. You can get the igniter from that. Many spray products use volatile fuels as propellants. Right Guard deodorant contains isobutane, butane, and propane as propellants. But the Aluminum Chlorohydrate, Cyclomethicone, Talc, and Silica Dimethyl Silylate may not be nice to breath after they have burned. Binaca Breath Freshener is my favorite, and you can find it everywhere. It contains isobutane and alcohol. The alcohol mist stays in the film can better than the gasses. But most of all, each push of the spray button meters out the same amount of fuel each time. The deodorant keeps spraying as long as you push, so you can't get the same amount of fuel each time. | ||

I am wanting to order the film canister canon kit and I don't see that option anywhere on the site. I have followed all the directions but the option to buy the kit is not available. Please let me know the cost and the product number so I can order several of them. Thanks, can't wait to try it. | ||

We are temprorarily out of stock on the wooden parts. But those are the parts you can easily make yourself... | ||

Hi, We purchased the igniters from your website, and want to make sure we're assembling things correctly. I see that I need two wires, and I solder them to where on the igniter? Thanks for your help. | ||

The igniter has one wire, and a brass cap at the bottom is the other electrode. Don't solder to that -- you will just melt the plastic. Just wrap the wire around it. High voltage does not need a soldered connection. | ||

Can i launch a biger thing with the film can cannon? What can i do to make it go higher and work every time? Will a biger thing slow it down? Pls help? | ||

Where did that fellow go who was going to build one with the Holly four barrel carburetor and the 55 gallon drum? Has anyone heard from him since? Maybe in this year's Darwin Awards? Take a bowl of water and place it in the middle of the lawn. The water only needs to be half an inch deep. Arrange two wires so that they form a spark gap, and place the wires in the bowl so that the spark gap stays above the water, but the wires go under the water, then up over the bowl, and into the house. Open one end of a dog food can, and feed the dog. Rinse out the can, and squirt some hairspray in it. You will have to experiment a few times to get the right fuel-to-air ratio. Place the can in the bowl of water, over the spark gap. Go into the house, and use a piezoelectric igniter connected to the wires to make a spark. The can will go up 30 to 120 feet in the air, with a satisfyingly loud noise, attracting the attention of law enforcement and parental units. Dogs will bark. Little children will cry. The can will come down eventually, making more noise. Repeat as necessary. | ||

Hi Simon, can i use a copper wire instead of brass wire if yes how can i use the copper wire So please give me the right information. I shall be thankful to you. | ||

If you have a spark, that's all you need. The type of wire won't matter. | ||

Hi Simon, I tried to make the wire long by adding another piece of wire and connected the an other wire to the brass cap and made a spark gap but it did n,t worked. So please give me the right information. I shall be thankful to you. | ||

Then you probably have to much losses along the wire. Try to reduce them, or use a shorter wire. |
