Radiation

How many times have you watched an old movie or cartoon that had some kind of wave drawn out on the screen to indicate radiation? Well, here is the real thing. The particles floating in the air move around and cluster where the decaying molecules have gone. This is real. This is how you do it.

The same thing happens in your body when you are exposed to radiation. These particles of alcohol are moved around enough to see them. The molecules are moved around in your body. Sometimes cells are burned or caused to fail or become cancerous by the same sort of motion you get in the cloud chamber above.
