It took about an hour of tweaking to get it all straight. Here are the things I figured out: between the can lid and pencil (or chopstick) you must use a bead or nut. If the stick is flat there is too much friction and no matter what it won't spin. liquid soap is essential. This greases the edges of the can lid for speed. The rubber band has to be wound really tight, like pulling the can lids in tight. Does this help? Ed, I had the same problems! It took about an hour of tweaking to get it all straight.
