Instructables
This is a projectile launcher that I made with my dad (yes, I did say dad, I'm only 13). If you work on it straight through, it will probably only take two hours at most. A friend and I started making these with a straw, tape, and a rubber band. Then we got to legos, and finally a more permanent version. this will shoot barbecue skewers at high speeds, but I'm not really sure about how far in feet it goes. You'll have to try it out =)

P.S. You might want to add flights ( like feathers on an arrow) so the skewer will fly straight. If it flies straight and true, this is a killing machine, so be careful (and send me a pic of how you did it).

Step 1: Materials

plank of wood
PVC pipe
2 copper pipe-fasteners
2 cup hooks
2 eye screws
1 long rubber band
tape
4 screws
a lot of barbeque skewers

Step 3: The Firing Mechanism

Picture of The Firing Mechanism
Get a large rubberband. place it so the sides are about 1" apart and wrape tape around the middle to make the catch. Stretch the rubberband through the eyes into the cup hooks. Now head off to the firing range!

Step 4: Firing

to shoot, insert a skewer into the front end of the barrel so the back of it hits the catch. Pinch the tape around the skewer, pull back, aim, and let go. I shouldn't have to tell you to be careful, because even if there aren't any flights, it can still pierce skin and mortally wound.

My cousin and I made something similar only it looked like a crossbow and had a clothes pin for a trigger. Definitely fun and dangerous, Every thing a 14 year old could ask for, right?

ya. my friend and i started with a straw and rubber band. we thought that was so cool, so we built one with legos for a more permanent feel. then i got the idea to make a more powerful one, hence wood and PVC. if you want me too, i'l post an instructable for the straw version. you can make it in about 5 minutes.
you should
