You don't need a whole lot of fancy tools and pieces of wood to make yourself quite a fun little catapult that has some real oompfh to it. This catapult was built strictly out of office supplies (By web visitor Brandon N.) and he has also built a trebuchet!

Brandon has also built an Office Supply Trebuchet! You can see pictures and get the parts list here: The Office Supply Trebuchet

Miniature Ballista Kit - Wooden Desktop Warfare Ballista

The ballista was the ultimate artillery weapon of the Roman Empire. Similar in appearance to a giant crossbow, it was powered by massive bundles of twisted horse hair. The bolts it fires would mow down enemies and fortifications alike. This kit is based on the Roman design. It is laser cut from select hardwood for easy assembly and reliable performance. This tabletop kit has been designed for simple assembly. Designed with interlocking parts, a simple, reliable trigger, high strength cordage and lightweight projectiles this ballista is incredibly durable. Three easy-to-follow rules for public demonstration are provided to ensure everyone's safety.

Sneaky Uses for Everyday Things: How to Turn a Penny into a Radio, Make a Flood Alarm with an Aspirin, Change Milk into Plastic, Extract Water and Electricity ... a TV with Your Ring, and Other Amazing Feats

Gonzo Gizmos: Projects & Devices to Channel Your Inner Geek - It's possible to use optics to roast a hot dog without electricity or a stove; to make a simple radio with just an iron, a few basic circuits and three shiny pennies; and to assemble a simple steam-powered boat with a plastic bottle, a candle, copper tubing and a nail. Of course, only die-hard science nerds would attempt these projects.
