Thermo-Sensitive Cloth

Cloths that change color with temperature, illustrating heat transfer concepts in physics education.

• Changes from dark blue to pink at 30 °C to show heat transfer visually

• Great for conduction, convection, and radiation experiments
• High sensitivity - Detects even small temperature changes for precise observations
• Reusable design - Each cloth is built for repeated use in the classroom

The thermo-sensitive cloths set offers a hands-on way to explore the principles of heat transfer. Designed to shift color from dark blue to pink at around 30 °C, these cloths make abstract thermal concepts visually accessible. Educators can use them to demonstrate conduction (e.g., pressing a warm object against the cloth), convection (e.g., passing warm air over the surface), or even radiation (e.g., placing under a lamp).

Their responsiveness helps students directly observe energy movement and temperature change, reinforcing learning through interaction. Each durable cloth is reusable and large enough (210×220 mm) to accommodate group activities and repeated demonstrations. This is an ideal addition to any science classroom focusing on thermodynamics or physical science fundamentals.
