Default How to make many small, controlled explosions?

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.

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.

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.
