The office would be intolerable without toy weapons. How else are you supposed to get someone's attention when they've got headphones on? The new Air Strike Catapult from ThinkGeek is the finest piece of desk artillery we've ever seen.
The $US15 onager-style catapult is based on the efficient, powerful design of Roman siege weaponry with added suction-cup feet to give your shots extra leverage and accuracy. Six spiky foam balls included. [ThinkGeek via Coolest Gadgets]
