Heres a link of what Im trying to do.

This is just my thought on this but I would guess there is an air cannon, fog machine, and a light involved. The fog is at the base of the cannon and the air cannon pushed the burst of fog out simulation gunpowder smoke. (personally I would insert a cross cut fabric piece about half way up the barrell to serve as a fog reservoir so you don't have fog constantly rolling out of the barrell)

I suspect the solenoid for the air cannon is electric and the light is probably wired in the air cannon's circuit so when the air cannon goes off so does the light. Now with that said you are probably dealing with a system that is wired for 120VAC and could use either a 120VAC or possibly stepped down for a solenoid that might be 24VDC or something to that effect. If it's lower than a 120VAC that get's into a few complications that have to be worked out but it can be done with a bit of work.

Hope this helps some...

That is awesome!

How long did a tank last you?

And how did you manually trigger it? The ones I've found are auto timed..

Just search Zon bird cannons you can get a manual trigger but its a little pricey. You will also have to have a 12 volt battery.

A 25 pound cylinder will last for 12,000 blasts.

Wow man that thing looks awesome. Can you safely point it at ppl? The biggest scare I've ever had was turning a corner at HHN and a turret gun was set up and shot air at me. I honestly believed I was shot!

You probally want to be a good 20 feet away from the front of it. Thats just because of the noise it does'nt blast flames or anything like that. When I say it's loud I mean it. By the way we did it outdoors.

There were no complaints, everyone was excited to leave alive. Thats the whole point in a haunted attraction.

I have run accross a problem before where the FM brought in a decibal reader and stated it was too loud and OSHA mandates hearing protection etc...

NOW here is where I'm going to help you out, below is the link to OHSA's website concerning hearing protection. I HIGHLY ENCOURAGE anyone that even thinks they will have a problem with this to print and keep the information on hand for quick referance. Please be sure to educate yourself to the fullest extent so when someone tries to tell you something you are able to know how to answer correctly. (something I learned from the military...lol)

Remember, knowledge is power and in knowing the codes, rules, and laws you are empowering yourself for success. :D
