Kitchen science: Salt makes ice melt a little, and the melting soaks up heat, so salty ice gets colder than plain ice and freezes the cream.

Squeeze the air out and zip the small bag shut, tight.
Fill the big bag with 4 cups of ice, then sprinkle in ½ cup of coarse salt.
Set the small bag inside the big bag and zip the big bag shut.
Wrap the big bag in a towel so your hands stay warm.
Shake it, shake it, shake it for five whole minutes!
