Bzzz! The Age Prediction Machine tests your date’s true age using high-pitched mosquito-like noises.
Fear not, folks in Japan have created a device to help answer that question.
The pocket-sized device, aptly called the “Age Prediction Machine,” emits high-frequency buzzing noises that are meant to help users determine someone’s age based on how well they can hear it.
The noise levels are broken down by age range: teens, 20s, 30s and 40-plus. People 25 and under will respond to the quieter settings, while those over 40 will only be able to hear the loudest.
The gizmo comes in pink and black and retails for around $10.
