How to Make a Paper Cup Anemometer - Simple Weather Science Project #10005 (License: Personal Use)

This illustrated diagram shows a classic four-cup anemometer constructed from disposable paper cups, plastic straws, a pushpin, and a pencil. The cups are attached to crossed straws that pivot freely on a central pin, allowing them to spin in the wind; rotation speed correlates with wind velocity. It’s a hands-on tool for teaching meteorology fundamentals and engineering principles.

Used in elementary and middle school science curricula for weather units, outdoor STEM activities, or DIY educational kits; matches user intent for simple, low-cost science projects, teacher resources, or parent-led learning at home.
