    Making an explosion

    I want to run a First Aid session, using some casualty simulation. This will run the week after the classroom session.

    My initial ideas are to take off the seniors into our kitchen (with an assistant, of course), apply the make-up while the juniors are being taught something else, in the hall next door.

    There will then be a bang, to simulate a cooker explosion or something, a bit of smoke, and we come staggering out to be 'treated'.

    The only thing is, how to make the bang? I guess I could just keep a banger from Fireworks Night, but I'm not terribly keen on the idea of letting off fireworks in the kitchen of the village hall. Any safe suggestions?

    Find a separate smoke source and use something like a balloon being popped for the bang. A lot will depend on the acoustics - a balloon being popped, heard from another room may sound enough like an explosion.
    Does anyone know what's going on?

    Record a suitable bang, and replay it through an amplifier. Making smoke is easy enough.

    You could buy smoke pellets from Screwfix etc... For an idea of effect a google search shows what ones are best.

    Probably need to be in a ventilated area though...

    For the bang? Mmm, I'd got for the banger in a wheelie bin (empty of course...) The bin will give more of a boom but remove the crack you get with fireworks.

    And, if it all goes wrong, you'll have real casualties to practice with...

    Please don't use "plumbers" type smoke pellets, whilst they work, the smoke they produce is fairly noxious stuff and will leave an aroma that is very hard to shift. Where abouts are you? I do have a theatrical smoke machine that I've used for fire drills which you could borrow if the locations work.

    +1 for using a smoke machine if you know someone who has one. The smoke is harmless.

    You can also get theatrical smoke bombs which are probably a lot less unpleasant than the plumbers version.

    (The timing of the thread title was impeccable - as i'd just been checking which gas cylinders at our HQ still have gas in them and which are empties... as people dont seem to like to follow the system of having a "full" side and an "empty" side in the gas cage. )

    some balloons with flour in them should suffice lots of noise and a cloud of dust

    Try jumping on the strips of bags filled with air that they often use for packaging. I did it once at work and the office manager nearly had a heart attack in the office next door!

    You could get a real explosion if a cloud of flour ignited!

    Who bets this is now being read with some amusement by those in Government looking to catch people on more serious threads along these lines?

    Thanks all, I'm on the hunt for a smoke machine. There are a couple of theatre groups nearby who should either have one, or know where I can get one. That seems like the way to go.
