i really wonder what the purpose of adding more wheels to it would do ... since ironically it doesnt make the original wheel spin any faster... then again they all spin at one rate.

it makes it stronger i think?

Think of it in terms of force. When a pinwheel spins, its arms apply a certain amount of force to whatever's in their way.

If you have a single-wheeled pinwheel, then the force of that one spinning wheel has to lift up the weight of the ball (read: resistance) and sling it up and forward.

By hooking up additional wheels, you make it able to apply that much more force to the ball. The reason why the self-rotating speed doesn't increase by much is that there's no resistance to overcome when it's self-rotating.

Take a look at my 5-wheeled sling on the previous page and see how it fares if you take out all the auxiliary wheels.
