Make Your Own Grappling Hook Launcher for Extreme Tree Climbing, Crime Fighting [Video]

MIT student and DIYer crreed shows us how to build a grappling hook out of a fire extinguisher and a nerf gun.

The gun is actually not that complicated to build; the hardest part, crreed says, is finding all the materials. Most you can probably find at a store like Home Depot, but others you might have to search for online. It's a lot of hoses and clamps, but the main power behind the gun is a dry chemical fire extinguisher and an N-Strike Raider Rapid Fire CS 35 Nerf Gun (seriously). You'll need some heavy duty tools, like a dremel, a hack saw, and a propane torch for soldering, but nothing a Batman wannabe wouldn't already have in his or her tool chest. Check out the video above to see it in action, and hit the link below for the full how-to. And, as always, be careful?this can be a little dangerous, so everything is at-your-own-risk.
