Saturday Science Sessions – Snow Ice Cream
A winter blizzard is the perfect time for a bit of chemistry and a tasty treat. It only takes a few minutes to whip up some homemade ice cream out of freshly fallen snow.
Collect approximately 8 cups of clean and fresh snow (remember you are going to eat it!). In another bowl, whip together 1/3 cup of sugar, 1 teaspoon of vanilla, a dash of salt, and 1/2 cup of either whipping cream or half and half. Then start mixing in the snow with a spatula. You may have to play around with the ratio of the ingredients depending on the consistency of the snow.
The mixture freezes as a result of freezing point depression. This happens when the freezing point of a liquid is lowered by adding another compound to it. Eat up and enjoy before it melts!
