Introduction: Paper Crossbow
There's a limitation to the materials to make crossbows. Here, you make it w/ simple materials.
It'll take about 36 hours to make one.

Step 1: Materials
You'll need :
-about 1 bottle of house glue
-A LOT of newspapers
-sturdy material for the firing mechanism
-creativity(optional(in case you want to modify it))
Step 2: Making the Body
-(x2) 2 foot long, 1 in. diameter newspaper roll
-(x1) 1 1/2 foot long, 1 in. diameter newspaper roll
Now put one 2 foot long roll on top of and perpendicular to the 1 1/2 foot long roll of paper 1/3 way of the 1 1/2 foot tube from top to bottom and stick it there(recommend you you tape it there during drying so it won't fall of). Then, put the other 2 foot long tube on top of it, perpendicular again and glue it in place.Then, attach the elastic band(bowstring)to the ends of the tube.You know how a crossbow looks like.
Use the pictures below if your confused
Step 3: The Supporting Arms
This is actually quite easy. I can't describe how to do it but you're gonna' have to glue it there using a glue gun
Use the pictures below, and cut the rolls at an angle.
Step 4: Firing Mechanism
Its not that easy, but it's simple and effective.
You can design your own, and make sure it's tough enough to hold back the elastic bowstring.
Mine involves a lever that has a kind of claw w/ a hole in the middle to allow the bolt to
slip into the bowstring, when fired the bowstring will push the bolt properly towards the target.
Use the earlier pictures for a complete reconstruction of the whole crossbow.
Step 5: The Ammo
The ammo is just a paper tube with an arrowhead on the tip, and at the back there's a slit to allow the bowstring to attach to the bolt.
I suggest you use a BBQ stick to roll a piece of paper neatly. Check my instructable "paper sticks made easy" to know how to do this.Anything sharp for an arrowhead is dangerous if traveling at a high velocity.
Step 6: Operation
Now, pull the bowstring to the firing mechanism. Cock it. Push the bolt until its attached to the bowstring.Then, pull/push the trigger!
-Use it wisely, safely, and carefully
-Don't shoot at the eyes
-If powerful enough, it can pierce the neck and hit the jugular.
-Just don't shoot at any, I repeat, any animal and/or people.
