1st I've heard of that. Breaking the marbles is a possibility I guess, but dropping them into a viscous liquid from a very low altitude would appear to me be a very hard way to do that.

My experience with marbles as a kid would suggest that somewhat rougher treatment might be required.

Getting the oxygen out of the bottle is the goal.

Personally I just use a little propane, easy but flammable, the volume is really low though, starting my gas stove burners wastes more and provides IMO a bigger risk. Others use nitrogen and its inert but it is tougher to get. There are also accordion style bottles.

None of these solutions are perfect but each markedly improves the storage life.
