This is a fun little Booby Trap that fires objects when a trip wire is pulled.
It is made from a few simple items that can be found around the office or home.

Needless to say, be careful what you fire at people.

Step 1: What You Will Need

3 Paper clips
Bottle Top
Rubber Band
Pliers (Needle-nose)
2 Drawing Pins
<p>This is genius, I super-sized this and made it fit in my school locker, attaching the string to the door. The string goes through to the outside through the secondary lock hole, with 3 chain links tied to it. On top of it all, there is a key-lock on the chain, preventing someone from simply disarming it. on the outside you only see a chain link and key-lock, but can still open easily. so open the locker and... snap! It slings a plastic long-dart straight at them. and to dis-arm it from the outside, remove the lock.</p>
<p>No friends will ever &quot;borrow&quot; pens again.....</p>
<p>not to shabby</p>
<p>i like it</p>
It didn't work for me! I think my paper clips were too weak or something?? When I hooked the rubber band in place it would just pull back the paper clips instead of stretching the elastic
<p>try using matchsticks and strengthining them with hot glue</p>
<p>Like LIke LIKe </p>

I think its an easy trap...
a great way to get fired! but still a great idea!
This looks brilliant! <br>I'm thinking of adapting this to fire pens (https://www.instructables.com/id/The-Best-Damn-Pen-Shooter-Period./). <br>If i can get it working i'll upload it, should result in pretty good accuracy <br>:)
YOUR A FREAKING GENIUS!!!!!!!!!!!!!!!!!!!!!!!
this takes foreverrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
Heat a nail over a fire and then poke it at the desired spot. It works, literally, like a hot knife through butter.
Or use the heated nail as projectile<br /> <br />
Your'e joking right?
no<br>hell make me very mad wake up to 500 of these with heated nails by your bedside
