There are mines that use floure and varrious other dusts, say you use a foam ball, you could hollow it out with and put in a plastic air sack surrounded by said powder so on impact the air is forced out carrying with it the powder. If I had a scanner I would post a picture of what I mean, but for now you'll have to use your imagination. Basically outer shell covered in small holes as outer layer, middle layer powder, center airsack.
