What is an avalanche backpack?
In an avalanche backpack there is an airbag system, which is supposed to prevent the skiier being buried by the snow / an avalanche.
How does an avalanche backpack work?
The principle behind the idea of an avalanche backpack is called "Brazil Nut Effect". This scientific effect states that, with simultaneous movement of several particals, the largest float on the surface.
This is exactly how an avalanche backpack should work. If a freerider is caught by an avalanche and he triggers the backpack in time, the inflated air cushion offers the athlete more volume and thus more "buoyancy". This should prevent a burial.
