Based on the provided information, you can construct a simple wind direction device, specifically focusing on the core assembly using basic materials like a pencil, eraser, straw, and paper plate.
Building the Core Mechanism
To create the part of the device that indicates direction and pivots with the wind, follow these steps using the materials mentioned:
- Prepare the Spinner: Take a straw and insert it into the pencil eraser.
- Ensure Free Movement: When inserting the straw into the eraser, make sure you leave enough space on either side of the straw. This is important so the straw can spin freely on the eraser.
- Create the Base: Use the pointed end of the pencil to pierce through the exact center of a paper plate.
These steps outline how to attach a rotating element (like the straw) to a stable base (the pencil and paper plate), allowing it to pivot and potentially show the direction of the wind if combined with other components (not detailed in the reference).
