How to Make an Anemometer: 7 Steps (with Images)

The anemometer is a tool made to measure wind speed. With a few simple materials, making an anemometer is a fairly easy craft project that can help students learn various scientific methods and subjects, such as experimentation, data logging, wind speeds, and physics.


Method 1 of 2: Making Holes in Cups

Make an Anemometer Step 1

Step 1. Drill some holes in the cups

Take 90ml party cups made of paper or plastic and use a paper punch to make a hole in each side. The hole should be approximately 1 cm below the edge of the cup.

Step 2. Drill holes in the center cup

In the fifth party cup, use the paper punch to punch two holes directly opposite, 1 cm below the rim. The holes must be identical and on the same level. Make two more, 0.5 cm below the edge, directly opposite each other and between the first two.

The final result will look like four holes equally spaced and perpendicular near the edge of the center cup

Step 3. Drill the bottom hole in the center cup

Use a straight pin to make a small hole in the base of the center cup. Then use scissors to make it slightly larger, to the point where you can fit a pencil that is loosely held.

Method 2 of 2: Joining the Anemometer Parts

Step 1. Place the straw inside a glass

Pass a straw through the hole in one of the cups with a hole in it. Approximately 1 cm of the straw should pass into the cup. Fold this leftover and glue it to the inside wall of the cup.

Do the same procedure with another straw and another glass with a hole. Next, you will have two cups with straws running through their side edges

Step 2. Pass a straw through the center cup

Pass the straw that comes out of one of the cups through the two holes (directly opposite) in the center cup. As soon as the straw comes out on the other side, pass it through another cup with a hole in it. When it has been inserted into the cup with a hole, let 1 cm of it pass into the inside. Fold this leftover and glue it to the inside wall of the cup.

Repeat this Step with the other cup and its corresponding straw

Step 3. Pass the second straw and its cup through the center cup

Pass the straw attached to the cup from one hole through the other two holes in the center cup. After going through the two holes, place another cup from one hole in the end of the straw. As before, allow 1 cm to enter the cup. Fold this leftover and glue it to the inside wall.

The two cups at the ends of the straws face opposite directions. When all cups have been placed at the end of the straws, all openings should face the same direction

Step 4. Place the pencil in the center cup

Push the rubberized side of the pencil through the center hole of the middle cup. Then push it up until it meets the intersection of the straws. Pass a pin through the two crossed straws and into the rubberized end of the pencil.

Avoid pushing the pin too far, or the anemometer will not be able to rotate when exposed to wind. Cross it just far enough to hold the straws together and the pencil eraser
