Take a Square shaped Paper and place it on the table.
Mark the center of your square paper with a pencil using a ruler.
Next, draw a diagonal line halfway between each corner of the paper and the center dot you just drew using your ruler.
Cut the diagonal lines you just marked on your paper with the scissors.
Fold every other point into the central dot and stick it using glue and place a pushpin into the paper.
Push the remainder of the pin through a straw/stick.
And it’s ready for fun.
Tip: Make sure to keep a little bit space between the straw and the pinwheel so it can rotate freely. Face the pinwheel against the air so it will rotate.
