It basically utilises a mass which is free to move, and a spring. In

like the pneumatic hammer action of a SDS drill[1]. The relatively
gentle movement of the container (by a swash mechanism in the drill)
is converted into a sharply released shock by converting its momentum
into compression of an air spring, and then allowing the spring to
release unrestricted. In the case of the drill; the spring
accelerates a hammer, and in the bottle; it accelerates the wine.

So, you are saying that if you forget the SDS you can use a bottle of Asda
Vino Collapso?

But how do you fit an 8mm dill bit into a bottle of wine?
