Introduction: Simple Bottle Cap Crossbow

In this Instructable I'll show you guys how to make an easy, simple crossbow from a recycled bottle cap in under 5 minutes. Enjoy, and be safe.

Step 1: Materials

Supplies:
- 1 Bottle Cap
- 2 Toothpicks
- 1 Rubber Band
- Tape

Tools:
- Scissors
- Swiss Army Knife

Step 2: Holes...

First you'll need to make four holes in the bottle cap as you see in the picture. Think of it as two sets of holes which are EXACTLY opposite each other.

To make the holes I used the can opener on my knife which has a very sharp point. I then expanded the hole by forcing my screwdriver through it.

IMPORTANT:make sure one set of holes is slightly lower than the other so that the toothpicks don't touch each other.

Step 3: Toothpick

Now put one toothpick through a set of holes and firmly secure with tape. This toothpick will act as the anchor for the rubber band we attach in the next step.

Step 4: Rubber Band

Now secure the rubber band around the toothpick with a Lark's head hitch. I tried my best to show it with pictures, but for further clarification, see this Instructable :

Step 5: Ammunition

In order to prepare your toothpick ammo for firing, cut off one of the pointy ends with your scissors. This will allow for better grip when firing.

Step 6: Loading & Firing

To load the crossbow, take your ammunition and thread it through the remaining holes. Now pull it back with the rubber band and fire away.

Step 7: Now What?

Well, there you have it, a pocket sized tooth pick shooting cross bow. You can use your shiny new weapon to annoy people at school, work or anywhere else you might find yourself. Thanks for reading my Instructable, don't forget to rate and comment. Hope you enjoyed it.

The hardest part for me was poking through the cap. I pushed a bit to hard on one of them. The bottle opener slipped and cut my hand. :( Good job though.

Thanks! Oh and nice candy wrapper >o<.
Just one thing I don't agree with, a restaurant full of people is the best place to shoot pointy things, you have tons of targets! Just get a seat near the exit ;).

its greatexcept for the elastic band part. if u could find another way to secure the band it would be superawesome

Nice, bu this is more of a bow than a crossbow. Crossbow has a trigger...

author
rocksalt2342 (author)Colonel882010-04-15

not necessarily, some ancient Chinese crossbows were fired as soon as they were pumped.

but yes, I agree that it is a bow.

ohh, and is there any way you could add a string to the toothpick so you could just haul it back in after shooting it?:P

author
tankguy (author)Capt. Fat2009-07-11

It might be a little tough, but you could get some thread and tape it just below the hole the tooth pick comes out of, then tape the other end of the string somewhere close to the end of the toothpick, Although if you were using a very strong rubber band (the big fat kinds) the tape might fall off.

Thanks ;)

How much power does this thing have? I'm asking because if I show my son, I don't want him shooting some kid in the arm and it breaking the skin. It is so cool, I know inevitably he will try and shoot someone with it.

author
tankguy (author)blacklion2009-07-11

It all depends on the strength of the rubber band you're using, If you don't trust your son with semi-dangerous projectiles I suggest you use a slightly larger, limper rubber band. Also, if you're worried about causing injury just snip the other end off of the toothpick as well, that way it won't poke anybody.

LOL! Awesome. Gonna have to play with this one. Wonder if there's any way to add fletching to the arrow to get some more distance/accuracy?

author
tankguy (author)Javin0072009-07-04

You could try making the holes it's fired from slightly rectangular to provide space for the fletching. You could try making the fletching out of tape like in this instructablehttps://www.instructables.com/id/Amazing-Toothpick-Darts/.

Javin007 (author)tankguy2009-07-04

author
miiwii3 (author)tankguy2009-07-05

author
Javin007 (author)miiwii32009-07-05

How could I possibly not use this for evil?

Oh, I get it..., I think.
