Key Benefits of the Crookes Radiometer

  • Excellent Physics Demonstration Tool

This apparatus provides a clear visual representation of light energy conversion. It is perfect for Junior Secondary and High School science classrooms in Kenya following the Competency-Based Curriculum (CBC) to explain heat absorption, radiation, and molecular gas movement.

  • Zero Power Required

Completely powered by photons and thermal energy, this device operates continuously under any strong light source. It requires zero upkeep, batteries, or electrical cords, making it highly reliable for remote school laboratories.

  • High-Quality Glass Construction

Crafted from premium, transparent glass, the radiometer provides a distortion-free view of the internal mechanism while ensuring long-term durability when kept on a level laboratory bench or display shelf.

  • Interactive Learning

Instead of reading about thermodynamics in a textbook, students can actively observe how black surfaces absorb more heat radiation than white surfaces, causing a localized pressure change that drives the vanes forward.

Crookes Radiometer (Solar Powered Light Mill)

Bring the fascinating world of thermodynamics and light radiation to life with the Crookes Radiometer. Often called a “light mill,” this classic physics apparatus features a glass bulb containing a fine pivot with four lightweight vanes. One side of each vane is highly polished or white, while the other side is matte black.
When exposed to sunlight, artificial light, or infrared radiation, the vanes spin automatically—the stronger the light, the faster they rotate. It serves as a captivating educational tool and an intriguing science desk toy for schools, physics labs, and science enthusiasts across Kenya.
Product specifications
  • Product Type: Crookes Radiometer (Light Mill)
  • Vessel Material: Clear, heat-resistant borosilicate glass bulb
  • Vane Structure: 4 lightweight vanes suspended on a low-friction metal pivot
  • Vane Coatings: Matte black on one side, silver/white reflective coating on the reverse
  • Internal Environment: Partial vacuum atmosphere
  • Power Source: 100% solar or light-powered (no batteries or electricity required)
  • Base Style: Wide, stable glass or sturdy plastic base for secure tabletop placement

Targeted Educational Concepts

  • Thermal Radiation: Observing how different colors absorb and reflect radiant energy.
  • Kinetic Theory of Gases: Explaining how the remaining gas molecules in the partial vacuum interact with the heated dark surfaces to create motion.
  • Renewable Energy: Introducing basic solar and light energy concepts to younger science students.
