How does it work? Just fill heavy whipping cream and powdered sugar in between the lines on the jar, depending on your desired serving. Add the creazy silicone agitators and shake. In 1 minute or less, voila, homemade whipped cream. It's fun, easy, ecological and delicious. Adjust the density with just a few more seconds of shaking. Whipped cream stores in the shaker jar for additional uses. Includes Glass Jar with lid & silicone agitators.
