Nuclear Fission
If nuclear fission is not controlled, then the rate of nuclear fission can become faster and faster. This starts a chain reaction where each stage of fission produces more and more energy. This could lead to an explosion.

Atom bombs
- Atom bombs use these chain reactions to create large explosions and release lots of energy.
