b: balls bobbing about
What:
"For a quickie off-the-cuff about the wave model I usually start telling people to put luminescent ping-pong balls in a swimming pool and turn out the lights ... you see the balls bobbing about: electromagnetism is like that, the balls are kinda like charges, only there's no water."
Useful?
