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

Picture of What you will need
3 Paper clips
Bottle Top
Rubber Band
Pliers (Needle-nose)
Ruler
String
2 Drawing Pins

Step 2: Straighten the Paper Clips

Using your Pliers straighten the 3 Paper Clips.

Step 3: Make four holes in the Bottle Top

Turn the Bottle Top upwards and then using one of the Drawing Pins, make 2 holes at either end.

Make the holes at one end approx 2cm apart, and at the other end 1.5cm apart.

Step 4: Bend a Paper Clip and insert into Bottle Cap

Now bend one of the Paper Clips using the Pliers so that there is a 2cm gap in the middle of the two 'arms'.
This is going to be pushed through the holes in the Bottle Cap that are 2cm apart, so that the arms point out the top.

Step 5: Bend the arms and attach the Rubber Band

Bends both the arms outwards slightly so they are at a 45 degree angle.
To attach the Rubber Band to the arms we need to roughly cut out a 4cm section of the Rubber Band and tie a knot in each end.

Now rest the Rubber Band between the tips of the two arms, then bend the tips of the arms around the Rubber Band and clamp them down. Making sure there is no room for the knots to slip though.

An image of the finished result of this Step is attached as the second Picture File.

Step 6: Bend the other Paper Clip and push into Bottle Cap

Exactly like Step 4, bend a Paper Clip but this time leave a 1.5cm gap in the middle.
Then push it through the two remaining holes.

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

a great way to get fired! but still a great idea!
This looks brilliant!
I'm thinking of adapting this to fire pens (http://www.instructables.com/id/The-Best-Damn-Pen-Shooter-Period./).
If i can get it working i'll upload it, should result in pretty good accuracy

Heat a nail over a fire and then poke it at the desired spot. It works, literally, like a hot knife through butter.
