I promise this story about microwaves is interesting.

Caption notes

Tom Scott starts with an old newspaper claim: was the microwave oven invented to rewarm laboratory hamsters? He outlines the familiar account of radar technology leading to a commercial microwave, then traces low-temperature research at a British laboratory. When the papers and anecdotes are difficult to reconcile, he interviews James Lovelock, who took part in the research. The video distinguishes the earlier commercial product from a device built for a laboratory need and discusses the limits of extrapolating from small-animal work to larger animals. This guide follows how Scott investigates the claim and distinguishes the two invention stories. Experimental outcomes, equipment and historical priority await independent verification.
