It sounds like a spoof, but this appears to be for reals: The Fukushima Plate—a sushi platter that comes with a built-in radiation detector:
The plate’s designer, Nils Ferber, explains how it works: Before using the plate, you set the level of radiation you’re comfortable with. If the plate isn’t glowing, your food has no detectable radiation. One glowing ring indicates a low level of radiation; two rings signals “significantly increased levels” of radiation. The dreaded red ring “tells you that the measured dose of radiation is beyond the limiting value you set before.”
What I’m wondering: Are you supposed to trot this plate out to restaurants? And if you get the red ring, do you send your food back? Awk-ward.
