just a guess
maybe somebody could manufacture a pre filled widget that "arms" itself when the bottle reaches a certain pressure..
search for guinness widget on this forum. The function of the widget has been discussed in pretty good detail (we even read the patent on the thing!)
In short: widgets go into the bottle "empty" (they contain gas, naturally... air or nitrogen, but they are not pressurized.)
Beer is put into the bottle with the 'empty' widget.
A drop if liquid nitrogen is put into the beer, and the bottle is sealed. The increasing pressure in the bottle pushed beer into the widget, compressing the air or nitrogen that was in the 'empty' widget.
When you open the bottle, the now compressed gas in the widget forces the beer out of the widget in a high pressure jet, and this releases teeny tiny bubbles of carbonation to give you a creamy head.
We have a theory here that the widget can be cleaned and reused. Just drop the 'empty' widget into a bottle, and put beer in.
We don't think
you need liquid nitrogen, because the pressure from normal carbonation should force beer into the widget to get the desired effect in the end.
