Can electricity or light beams cook a steak to perfection?
In short: In this experiment, Andy and Greg Foot explore the physics of cooking using mains electricity and focused light. Discover how energy transfer can turn ordinary objects into high-intensity heat sources.
The demonstration explores the concept of joule heating, which occurs when electrons are forced through a substance like a salted steak. Because meat is a poor conductor, the electrons must be pushed with significant force, transferring energy through interactions with the meat's atoms and molecules.
The team also investigates the power of parabolic shapes. By using parabolas, incoming beams of light are focused into a single central point, concentrating energy that would otherwise be spread across a wide area into one spot of intense heat.
