Ig Nobel Prize: the most ridiculous inventions and more

Why is the "Ig Nobel Prize" awarded? The creator of the prize, Mark Abrams, answered this question like this: "The Ig Nobel Prize is not about the best or the worst. It's about the things that make you laugh first... and then make you think." It's hard to disagree with him, as thanks to its laureates we now have lactose-free milk, blue jelly, and a device that translates dog language into human language. We learned that music in elevators prevents colds, that an entire European country can be rented for a corporate event, and that in India there is an association of dead people fighting to be recognized as alive again and restored to their rights. The author of the popular science portal InScience.News, Yana Hlyustova, will tell us about the most extraordinary discoveries and inventions.
