Perhaps as well to mention that the 'active ingredient' is laughing gas
 - N2O - which froths up cream (and evidently yoghurt) nicely.
 The gas is purveyed in capsules of about the same size as the CO2
propellant gas which is used in BB guns etc.

But if inorganic chemistry is not your thing, how about
Danone's Activia - which makes much of its culture - Bifidus Regularis?
