The Physics of Sustainable Electricity Generation

Pinwheel Experiment

Materials needed:

 

 

 

 


Step 1: Fold paper in half, diagonally.

 

 

 

 

 

 




Step 2: Fold it in half again, the opposite way.

 

 

 

 

 

 

 

 

 

 




Step 3: Cut along the folded lines, stopping halfway between the edge of the paper and the centre.

 

 

 

 

 

 

 




Step 4: Fold one corner of each triangular section into the centre, taping it down.

 

 

 

 

 

 




Step 5: This is what your pinwheel will look like when all four corners are taped down.

 

 

 

 

 

 

 

 




Step 5: Place the straw on the back of the pinwheel and secure it with a straight pin.

 

 

 

 

 

 

 


 

 



You now have a working pinwheel. Enjoy! It works best by walking with it.
