How to make a REALLY powerful rubber band gun

Picture of How to make a REALLY powerful rubber band gun
My friend and I made a rubber band gun. Unfortunatly his Mum threw it away before I took any pictures, so I had to make artists impretions. Beware, this is REALLY powerful (I dented a car window!).

Step 1: What you will need...

Picture of What you will need...
You will need...

1 recangular, thin piece of wood (approx. 1.7m)
Lots of thick rubber bands (you tie 2 togeather)
Lots of small rubber bands
colthes peg

Step 2: The notch

Saw a notch in one end of your wood. Make sure the wood doesn't overhang the notch.

Step 3: The Trigger

Place your clothes peg on the wood (with the notch), making sure it is square, and attach it to your wood with your small rubber bands (THIS HAS GOT TO BE STRONG as it will be under great stress).

Step 4: The Ammo

Now you use the thick rubber bands. Tie 2 togeather, put one end of the rubber band in the notch, and put the other end in the clothes peg.

Step 5: You're Done!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Now you're done! You can have fun with this BUT BE CAREFUL, this can hurt!!!!!

It doesn't really dent it, but makes a mark on it which has gone in a bit. Got into so much trouble with that!! And no, I'm not Uncle Charlie.
my uncle taught me how to make this... you dont happen to be uncle charlie, do u? we put a nail thru the peg to secure it, then took the metal spring out of another clothes peg and attached it to the rubber band, makes it alot more dangerous i got the rubber band metal part stuck in a tree trunk good instructable
