Thanks for that link. I like the idea of water jets on a motion sensor. That is do-able. Maybe also add strobes too.
...And maybe play a recording of Preznit Dubya giving a speech. If that doesn't put them to sleep, it will bore them to the point of suicide.

I like the ideas about the electric eels. Anyone know where to get one? And how much does the electricity cost to run one?

I went shopping for the parts for water jets on a motion sensor. Someone explain this to me: A motion sensor costs $18 and a light set costs $16. On the shelf lower is the light and motion sensor combo for $11. Of course since I need a light for my outdoor tanks and a motion sensor for the pool, I bought the separate packages

Probably for the same reason toner for your printer costs $40, but a new printer with toner only costs $50.
