Is this stupid? Answered

If you know about those little banger thingies that you throw on the floor and they bang, what are they composed of? I had opened one up and I had found rocks.... also I had set light to one of those nifty things and BOOM! Why did that happen? They combust when they hit the ground, or is my match at a really high temp.?

Typically, one of the low-power "touch explosives" -- ammonia tri-iodide or similar. Either heat or impact can set them off, as you discovered.
