Pencil Propeller

Today we learn how to make a DIY toy.
This call Pencil Propeller. 
This is a more high-tech version of a great toy.

Begin with a square of origami paper, white side up.


1: Cut the paper in half.


2: The next steps magnify one end of the paper.


3: Fold and unfold four separate folds about 1/2 inch(1cm) from the edges of the paper....


4: ....like this. The next step magnify a corner.


5: Make a short diagonal like this...


6:...simply by squeezing a corner between your thumb and first finger. Repeat at each corner.


7: This is the result. The corners don't have to be very neat.


8: Repeat with the other corners.


9: Take a pencil that includes an eraser in the top end. Then take a thumb tack or something similar and push it through the center of the paper into the eraser.


10: Hold as shown, and then walk briskly forward. The paper will begin to spin around on the end of the pencil! You can up the scale and use a large 2 x 1-foot rectangle of newspaper pinned to the end of a wooden broom handle... but you'll need to run fast to make it spin!


Done!
