I'd like to see more medical data.

Looks interesting to me. I would think since it is using the top of the head as the push point, it wouldn't put any pressure on the neck or spine. Ripping your ears and the tip of your nose off maybe, but guess if you can't breath that would be minor.
And it could be drunken party fun to use compressed air and shoot for distance.
