1: a propellant used in whipped cream canisters. (probably safer than co2)

2: sold in "whippets" or "igi" bulbs, which are Meant to be cracked into a canister full of cream, and then released whipping the cream.

3: users of the whipped cream canister often use an empty canister, release the bulb into the canister and then inhale the gas from the canister. When inhaled often a "nang" noise is heard and a strange sensation encompases the entire body, this lasts between 10seconds and 2 minutes from one bulb. This is not Physically addictive, but it is often such a good high that users become mentally addicted.
