What's your favorite Batman Gadget?

[13doctorwho]

I've made so many Batman gadgets it's hard to choose a favorite. Minus the Batarang, the Grapple gun, and the vehicles, what's your favorite. I'm thinking more hand gadgets. I mean the Batmobile is awesome, but not many of have the resources to make one (damn Matt Munson).

So start posting.

I like the grappling gun from Batman The Animated Series. It's such an illogical design, but it looks cool, and the sound it makes is really satisfying.

I always liked the highly impractical gauntlet from batman (1989)

Bat Shark Repellant from the 1966 movie, hands down. I like that it is areosol, so you can't actually use it underwater, only dangling from a helecopter.

What about those spiky bombs the armored batmobile droped. They'ed make a neet display piece.
