I've always been tempted to sulfite/clean/bake out at 500F some sand
and pour that into a carboy. Those many nucleation sites should cause
an immediate explosion of gas (which means really slow addition)... and
if it were clean sand there should be no impact in taste.

I saw something rather funny about mento's being used to release all
the gas from a diet pepsi. Interesting...

If you are baking at 500F, do you really think sulfiting is going to be
needed? Nothing organic can survive at that temperature LOLOL.

I can picture the sand shifting during the next racking, stirring up
some settled sediment. Hmmmmmmm...
