Leslie’s Cube – Heat Radiation Demonstration (Tinplate, 130mm Sides)

This high‑quality Leslie’s Cube is designed to compare radiant heat emission from surfaces with different finishes. Made from tinplate with 130mm sides, each face has a unique surface: polished black, matt black, varnished, and white. The cube is filled with boiling water, and infrared sensors are used to observe the differing radiation outputs. Supplied with stopper (7mm bottom diameter; 12mm top).

Key Features

• Tinplate cube with 130mm sides for uniform heating
• Four contrasting surfaces:
  • Polished black
  • Matt black
  • Varnished
  • White painted
• Fitted with stopper (7mm → 12mm)
• Ideal for thermal radiation comparison

Ideal for Physics Lessons

• Comparing emissivity of different surfaces
• Understanding heat transfer by radiation
• KS4–A‑Level thermal physics demonstrations

An essential apparatus for teaching emissivity and heat radiation in an engaging, hands‑on way.
