Race To The Bottom

I was at a local mall when I saw one of those spiral wishing wells. If you don't know what I'm talking about, here's some video:



This is literally throwing your money away.  But then, I guess that's what wishing wells are all about.  And, to be fair, you do get a bit of a show--more than what a regular wishing well, or a fountain, provide.

There's a little card there suggesting you try different coins to see if they go down at different rates.  I don't think so. I'm willing to try a penny--after all, they're worthless--but I'll keep the quarters. And dimes.  And even nickels.  They disappear quickly enough without any help.
