An Airbag for your Head

What recent Swedish invention costs $450, comes in a variety of styles, can be used only once and inflates upon impact?

If you guessed Hövding’s inflatable bicycle helmet, you’re correct! It’s designed for all those fussy cyclists out there who like their brains but love their hair. The helmet has a built-in motion sensor and inflates in a fraction of a second, protecting your head from a nasty fall.
