The rules state:<br/><br/><em>&quot;All types of rubber band-powered entries are eligible, with one exception: no weapons of any kind.&quot;</em><br/>
How lame. Will a youngster be bound for a life of crime because he saw a rubber band gun here? You can also rule out missiles, bows, crossbows, catapults, sligshots, etc.
I don't think its an Intructables rule, I think it's a Klutz rule. You don't like it, take it up with them.
For a perfect entry example go here :<br/><a href="http://www.instructables.com/id/Robot_Racer/">http://www.instructables.com/id/Robot_Racer/</a><br/><br/>lolololol<br/>
