Magical Match

Produced by the Institute of Physics, this Physics to Go video shows a short demonstration that can be used to engage your students. The teacher notes include the equipment needed, tips and contain a full explanation of the physics involved.

In this demonstration, the uneven contraction of a match causes it to bend. The same type of uneven expansion and contraction that is common in many thermostats that contain a bimetallic strip.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
