What should I buy at Think Geek?

Apparently Think Geek gave me a complimentary gift certificate for $5 a year ago, a fact which somehow slipped my notice. Anyway, it’s about to expire in a little while, and I should probably use it. What cheap (~$20 or less) gadget/gizmo/thingy do you think I should get?

I got a marble roller coaster set with a gift certificate. It’s very cool, although not for the easily frustrated.

Plush microbes. I have “beer yeast”.

I have the yeast one too. My cat loves wrestling with it.

I really like the idea of the TV-B-GON

I have the Binary LED Clock on top of my computer. As the ad says “Yes, It’s A Clock. No, Your Mom Can’t Read It.”
Or there’s the Wind-up Bender toy. For when you need to tell someone “Bite my shiny metal ass!”

I have the smart putty. And I bought the flu plush microbe as a white elephant gifty last Christmas when we were all having the flu vaccine epidemic freakout – figured it was appropriate. :smiley:

I’ve been coveting the Antworks Space Age Ant Habitat at ThinkGeek for some time now, but it’s $20, and if you go for that, it really would be so much more fun with the blue LED base (another $13, would be even cooler if it were USB powered). Of course, then you’d have to get ants too…

Eh, I guess the plush microbes would be a more economical idea, but that ant farm is just too cool.

I have several of these. It is an optical mouse with a little yellow rubber ducky floating in a little blue sea.

Juuust under twenty bucks, they haveLaser tag , with grips made for an adult’s hands.

Why, a Leatherman tool, of course!

The scissors on this are awesome!
