Picture of Assassin's Micro Crossbow

This article of desktop weaponry accommodates multiple rounds of ammunition, launches exploding tipped cross-bow bolts, and slings wooden matches over 30 feet away. In this project we're turning some ordinary household items, into a surprisingly versatile, micro-crossbow.

Step 1: Watch the Video!

WARNING: The depictions of launching sparklers in this video are for demonstrational purposes only and are not intended to be duplicated. While this little contraption is micro-scale, it can still be dangerous to some degree. Use care and caution when choosing your ammunition, be aware of your surroundings, and never shoot at people or property. There may be risks associated with these projects that require experience, and/or adult supervision. Use of video content is at your own risk.

Step 2: Sticks and Templates

Picture of Sticks and Templates

Start this project with a handful of popsicle sticks, and a template showing how to cut them.

You can get a free template and instructions here

Once the popsicle sticks are all marked, use something like a pair of gardening shears to cut the pieces to size without ever having to make a single measurement.

When all the pieces are cut, paint them completely black with a permanent marker.

The ink will probably take just a minute to dry, so now would be a good time to round up some metal hair clips.

Step 3: Limbs and Support

You'll only need 2 of them, and with a little manipulation, the inside clip will break off cleanly at the bottom.

The first step of assembly is securing the clips to the wooden supports with a bit of hot glue, so that when it cools, the limbs arch away from each other in a bow shape.

Next, go ahead and add some hot glue to the inside of the arch and press the second support firmly into place.

I cleaned up the excess glue with a utility knife to get the look you see here.

The next part focuses on making the pistol grip.

Thanks so, so much for this! I'm a medieval reenactor so this is right own my street! Made a larger version for my partner's birthday present out of basswood and large hair clips and it worked out quite well; see what you think :) The bolts are made from kebab skewers :P I'm going to be making a wrist mounted one too, attached to a leather gauntlet (I do like making leather things) with a hand operated trigger system. Looking forward to trying it out! :D

If you are required to give an email to get the template, I do not consider that to be free.

Very cool instructable. You could insert a needle into a match that has the head cut off (or just the back end) then it could stick into things.

Not to sound stupid, but how are you supposed to fire it? Just push up on the string?

yup you just push up on the string and it should catch and launch the bolt

I used 3mm jolt head nails with their heads cut off for bolts. They are a bit heavy, but look awesome when you load them.

Nice going King. How much of a spark do those popper things make?

will someone send me the template?

This thing is awesome. I glued the slanted side to the bow part and it works just fine. As you may see on the picture I made a little clip wire to keep the string taunt. I also made an arrow by glueing a pellet for pellet guns on to a section of skewer.

thank for this great project and the upgrades . also thanx for the sonic dad link which got me 12 free projects


In high school we stuck two matches in the half of a ball pen that contains the spring. Then light the matches, and within a second the heads shrink because they burn and the two burning matches are launched by the spring in the pen. They make it easiliy to the other side of the classroom. The only preparation one needs is a tiny little rope to prevent the spring from escaping the pen.

Here is my own crossbow it uses a metal rake tine and popsicle sticks, with a little foam for decoration. I use sections of wire coat hangers flatend and sharpened on one end. On the whole its pretty dangerous lol



How do you fire the gun one not the crossbow (the part in Making An Upgrade.)
