A simple test used to check whether a carton or similar packaging item contains liquid or ice.
To perform the test, pick up the carton and shake at a moderate pace. You should feel a constant force as the liquid hits the edge with each shake. If you feel something hit the carton from inside, there's ice inside, and if you can't feel any force, the contents froze over.
Repeat the test with different cartons until you find one you're satisfied with.

The iced carton test works best at schools that store liquids like milk and juice inside containers.
