Creating a plant-based anemometer is a fun and eco-friendly way to measure wind speed using simple materials like outdoor plant boxes. Here’s a step-by-step guide to build your own sustainable tool:

1. Gather Materials: You’ll need small outdoor plant boxes (preferably lightweight), wooden dowels, a sturdy base (like a wooden plank), and a rotating mechanism (such as a ball bearing or a nail).

2. Assemble the Cups: Attach the plant boxes to the ends of the wooden dowels to act as wind-catching cups. Ensure they’re evenly spaced and balanced for accurate measurements.

3. Mount the Rotating Mechanism: Fix the dowels to the base using the rotating mechanism, allowing them to spin freely when wind hits the plant boxes.

4. Calibrate Your Anemometer: Use a reference anemometer or wind speed chart to mark rotations per minute (RPM) against known wind speeds.

5. Test and Adjust: Place your anemometer in an open area and observe its movement. Fine-tune the balance or cup angles for better accuracy.

This DIY project not only promotes sustainability but also offers a practical way to monitor wind conditions for gardening or educational purposes. Happy building!
