Amazon.com has a great price on 50-packs of whippets right now.
Today I learned that if you really, really, really like whipped cream (and I am not implying that this product can be used for any other purpose), you can buy 50-packs of Whippets for $99,999 on Amazon (Regular price: $28.99). Put me down for three, thanks.
Whip-It! Brand: The original; Reflecting over 60 years of manufacturing expertise. Food grade N2O is used as a propellant for whipping cream, which dissolves in the liquid cream. As the cream is released from the whipper, the gas expands and in doing so whips the cream into foam.
