Introduction: K'NEX Basic Catapult

Picture of K'NEX Basic Catapult

Hi! These are the instructions to my catapult. It is an original design and can fire anything! It goes quite far and has an easy fire mechanism. It uses very few parts and is easy to make!

I became pro for two years yesterday, and I have given away 2 of my 40 patches, and I doubt I will ever give them all away without hosting a few contests. The contest is to submit an Instructable (Must have instructions) that is Christmas themed, and send the link to me by private message. The winner will get a specially made patch.
The runners up will be featured in a guide.
The deadline is January 12th 2011.

I'm pretty sure that's all you ever say! Try to include some meatiness into the comment rather than just 'nice'!

Tf? He doesn't have to leave an entire essay on this piece of garbage. "Nice" is actually being generous. This thing hardly works at all. The only way I got it to work was by modding it and even then it still had a hint of garabage left in it.
