As the title states.
Why is N2O used in canned whipped cream?
What's special about Nitrous Oxide?

The gas is extremely soluble in fatty compounds. In aerosol whipped cream, it is dissolved in the fatty cream until it leaves the can, when it becomes gaseous and thus creates foam. Used in this way, it produces whipped cream four times the volume of the liquid, whereas whipping air into cream only produces twice the volume. If air were used as a propellant, oxygen would accelerate rancidification of the butterfat; nitrous oxide inhibits such degradation. Carbon dioxide cannot be used for whipped cream because it is acidic in water, which would curdle the cream and give it a seltzer-like 'sparkling' sensation.

Haven't you seen what N2O or 'NOS' does to your car?




Watch 'The Fast and the Furious" for more demonstrations. :)

Ah, that explains a lot - when I was little I sometimes used to sneak to the fridge and squirt the aerosol cream into my mouth. I'd noticed when doing this a strange "taste" or aroma that came out with the cream but rapidly vanished.

Now I know what that was!

Nitrous oxide (N2O) is a dissociative drug that can cause analgesia, depersonalization, derealization, dizziness, euphoria, and some sound distortion.

You didn't happen to feel any of those effects did you? :)
