Binder Clip Blaster

Ah yes, the Binder Clip Blaster, one of the most concealed weapons, as it is literally just a binder clip. It also goes off with a nice "BANG" to suit its nature.

Literally just a 25mm binder clip. Bigger ones work, but smaller ones don't as the middle part doesn't support the projectile.

Also a ruler and lightly coloured permanent marked, but those are optional.

Hold the binder clip upright, and take out one of the wires from the sides, and apply pressure to the sides of the wire. Then, slide it into the binder clip horizontally.

To prime the weapon, push your index finger to the opposite end of the binder clip, in the end without the wire. Push hard, and using your thumb, push the wire until it touches your index. Don't push further. Finally, make sure that the wire is centred, so that it will fire at max momentum.

Hold the binder clip with your hand, maybe both for stability, and make sure not to cover any holes. Once you have that, aim the weapon, and use your thumb to push the wire further in. It should make a bang sound, and the wire should fire. Even if it is not sharp, please don't aim at people's faces, and know that I am not responsible for anything that happens as a result of making this project.

This is optional, and also when the ruler and permanent marker. First, draw a line across the width of the binder clip. Once that is done, measure it with a ruler, and mark the centre of the line. Once that is done, draw a line perpendicular to the first line. To mark the wire, slip it on the bottom of the binder clip, and mark the centre using a ruler.
