My daughter brought me a little 4th of July toy. A pinch of pebbles wrapped in a bit of tissue paper. One throws these at the ground and there is a small popping explosion. I had guessed there was a bit of gunpowder mixed in with the pebbles, but when she and I opened one, there was no evidence of any black powder. How do these things work??

Look up "silver fulminate", and you will get your answer.

There must be a kind of explosive/flammable substain in the pebbles or the pebbles themselves. When you throw the "snapper", the pebbles crash betwen them and produce sparks, and that the responsibles for igniting the explosive/flammable thing.

They're basically gun powder. There are rocks (flint and a gun powder concoction that's solidified into rock) that when given energy (snapping them) they make a chemical reaction releasing H2O and other chemicals (not harmful). So a small explosion is the result.
