How to make many small, controlled explosions?

Smoke Marijuana · #1 2007-07-12, 22:05

My friend is making a film, and for one of the scenes he wants sand to fly everywhere. The idea is to put some kind of small explosive device under the sand (possibly many small devices), to create a sand storm on demand. Can this be done? I am a complete noob to explosives so I apologize for the un-researched question.

To make the problem more difficult, we have access to only house hold chemicals, and things that normal people can buy. I have no good hook ups for chemicals, and there is a budget on how much this can cost.

I don't think this can be done easily or possibly at all, but still I told my friend I would get some advice.

Advice is greatly appreciated, thanks.

when we did it we built what we called a sand storm tent which sounds like what you need
"accuire" one of those carport things and a big fan set up fan inside carport on beach turn on and insta storm

An explosive charge will only create a small poof of flying sand. A truly massive one could suspend fine dust for several hours, but that's not what your looking for, and even so ... league issues right?

So you're looking for a large fan or jet engine.

would sticking a roman candle in the ground with sand ontop or pouring powder from a roman candle under sand do the trick?

sorry for all the questions, i just wanna blow shit up for a battle scene

Yeah, any small salute will do.
If you want a lot of takes, some tubing, a mesh screen and some loose sand would be the better option.

hmmm so just a bit of powder in a small tube with a fuse...

sounds like a plan
