Besides its obvious utility, this morning I discovered a new hobby:
some little bastard ants had decided to raid a fleck of chocolate on my desktop. And my little friend was handy.
Suffice it to say that ants don't do any better with 8M V than people do, and I understand Thor's motivation a bit better.
On my next day off, I need to go find a red ant hill.
Perhaps I'll video the result, and send it to PETA.

And I want someone to invent one of these things as a doorbell greeting for door-to-door peddlers.
