  - convert nuclear energy
* Some bomb fuzes require a continuous supply of electrical power during flight.
* Some bombs can be the size of a small car
  - have destructive forces
  - use fission reaction

+ Shock wave: Fluid mechanics
  * A 'shock wave' is when lots of energy comes from a very small spot. Bombs create shockwaves. A shockwave happens because the energy pushes air really fast, and then the air can hit things. Bombs are made more dangerous because of shockwaves.

### device | bomb:

Atomic bomb
