The easiest  way to make a whirligig mobile from reused paper,
your kids will love to make and set spinning. 

  

When you're finished, you can throw it in the air

or hang this whirligig mobile from the ceiling to see it spin !

• Cut a strip of reused paper about 12 cm wide and 18 cm long.
• Measure about 4 cm from the left end and mark as A. at the vertical center, cut horizontally as shown in the picture then also measure and cut from the right end the same.

Bend the paper.

Slip A. and B. together.

The paper is locked as a bow.
Now, just throw it in the air and see it spin horizontally when falling down.

It easily catch the wind and get spinning pretty fast.

    
  Make several in different colors papers,
differnt dimension to make it spin faster.
(I think my wind spinner is too fat !)
