Recent research tells us that a well made bottle of French champagne when opened will release around one billion tiny bubbles of carbon dioxide. Pondering this made me realise that should all of that gas go up as one large bubble it would be 50 kilometres in diameter. Now in any day there would be on average about 800,000 to 850,000 bottles of French champagne opened globally which combined pops out as a truly big bubble, much bigger than earth.
