Would be interesting if you could get a true -R though!

I spent years perfecting a bar magnet with only a North pole. (Monopolar) I set
it down on a table for a moment and it promptly took off for Antarctica. I
haven't seen it since.

I've been making them with only South poles for the last year, but have them
all tied down. I'm going to release them on December 24 and give Santa a big
surprise.
