Introduction: Soda Can Windmill

Picture of Soda Can Windmill

Inspired by an unknown person who made windmills out of used beer cans.

Step 1: Materials

Picture of Materials

1. Empty soda can
2. Can opener
3. Plier
4. Wire
5. Scissors
6. Yakult / Vitagen drinking straw

Step 2: Step 1

Picture of Step 1

Cut open the top of the soda can with the can opener.

Step 3: Step 2

Picture of Step 2

Make a hole at the bottom of the can. Cut a short section of the Yakult straw and insert halfway into the hole to act as a washer. The windmill can spin faster and smoother this way.

Step 4: Step 3

Picture of Step 3

Using the scissors, cut the can into 8 equal strips as shown in the picture.

Step 5: Step 4

Picture of Step 4

Fold down each of the strips to make the windmill propeller.

For each fold, bend the strip slightly in the same direction so as to create an angle of attack for the propeller blades relative to the airflow.

The propeller pitch will affect the windmill performance. Generally, fine pitch will work well in low wind condition, while coarse pitch allows the windmill to spin faster when the wind is strong.

Step 6: Step 5

Picture of Step 5

Insert the wire into the straw and bend it to secure the windmill.

Attach the windmill to any stick or stable structure and place it facing into or away from the wind direction.
