Homemade Ice Cream

06 Jan 2009 / 1 Comment / in Chemistry, Featured/by Carl

Making ice cream is actually pretty easy to do and you don’t need any fancy equipment if you’re just making small batches for fun. This is a great Saturday afternoon activity. You’ll be surprised at how good it actually tastes. Just keep in mind this is not low-fat low-calorie. In fact you’d be better off calling this the full-fat high-cal version. This recipe is enough for one person to make one dish, but you can always scale it up a bit so you can share with friends as well.

Try to grab some in your hand and it will form a solid ball in your palm just until you release the pressure, then it will flow out between your fingers. Materials that behave this way are classified as non-Newtonian liquids because their flow properties are not described by a constant viscosity. The name Oobleck comes from the 1949 children’s book, Bartholomew and the Oobleck, by Dr. Seuss. In the story, King Derwin is bored with the four types of weather in his kingdom. So he tells his Royal Magicians that he wants something new to fall from the sky.
