Bomb Mechanism

Chain reaction

Imagine you have an atom, and you hit that atom with a neutron. What will happen will be that the atom which was hit will release 2 particles. 

Now, make a family tree, for each member of the family, add to children, do this till you get tired. After this, change the people's faces to the image of an atom. Hit the Great Great Grandparent with a neutron, the Great Great Grandparent (first atom) will release to particles, his 2 particles will cause the 2 Great Grandparents to release 2 particles each. This 4 particles will hit the 4 Grandparents, causing them all to release 2 particles each. This chain reaction can go to infinity, and each generation will emit double the particles as the last, affecting double the atoms. This chain reaction can be used for 2 things: 

The good: Making nuclear energy (the cleanest energy of all).

The bad: Making an atomic bomb, will cause death and destruction.
