Title: Whipped-cream charger
Passage: A whipped cream charger (sometimes colloquially called a whippit, whippet, nossy, nang or charger) is a steel cylinder or cartridge filled with nitrous oxide (NO) that is used as a whipping agent in a whipped cream dispenser. The narrow end of a charger has a foil covering which is broken to release the gas. This is usually done by a sharp pin inside the whipped cream dispenser. The nitrous oxide in chargers is also used as an oxidizer in hybrid model rocket engines.
Question: is nitrous oxide still used in whipped cream
