Tape (for the Large 3-blade and Classic Pinwheel designs)
Wooden stick (dowel rod or square)
Instructions are included on the templates. Here are some tips for best results:
Try to fold the blades to the same exact angle; this balances the “push” from the wind and it will spin faster.
Heavy cardstock is recommended; regular office printer paper is too thin to work well.
For prolonged outdoor use, transfer the pattern onto a plastic “For Sale” sign available at many hardware stores.
Experiment with folding the blades to different angles to see the effects. This works best in front of a fan at a fixed distance. Note the amount of time it takes for the blades to reach full speed between different blade settings.
Try taping a penny onto each of the blades of the Large 3-Blade design. Hold it in front of a fan and note the amount of time it takes to reach full speed, and then try to turn the pinwheel away from the flow of wind. Compare to the pinwheel without the pennies. This illustrates the advantage of lightweight wind turbine blades like those on an Electric PinwheelTM.
