How does an onion bomb work? How does it explode when thrown?

Onion bombs are quite popular in India and are burst during the festival of Deepavali.
I have uploaded a picture of how the bomb looks. It bursts when it is thrown on a hard surface with some force. Small children can get it to burst by throwing it on the floor - which adds to its charm and fun quotient.
From observing exploded onion bombs, I have noticed that there are small stones inside the bomb. The stones and other chemicals are wrapped tightly in a cloth.
I am curious to understand how these bombs explode when they are thrown against the floor.
