How to explain stationary waves to someone unfamiliar with them

[MrRamage]

How would be a good way of explaining Sationary Waves to somebody who does not know what they are? I'm talking analogys, presentations, ideas.
I have a good knowledge of them, but am struggling to explain them to my peers.

Perahps it may be worth while sharing your 'good knowledge of them', that's if its not to much of a struggle?

Then I'm sure you could just as well send your peers here, and let them see your shared knowledge.

Get a slinky spring and get two volunteers, one person to hold each end. Then get them to wiggle it until a stationary wave appears. By wiggling it faster, you should also be able to demonstrate the first few modes.
