How does salt lower the freezing point of water?

snow-roadsWhen you are making ice cream, the temperature around the ice cream mixture needs to be lower than 32 F if you want the mixture to freeze.Salt mixed with ice creates a brine that has a temperature lower than 32 F. When you add salt to the ice water, you lower the melting temperature of the ice down to 0 F or so. The brine is so cold that it easily freezes the ice cream mixture. But what about the places like Antarctica, Greenland, and Canada the fresh water in the air freezes to snow and falls. Read More

Covestro polycarbonate used to make precision nocks for archers

covestro-archeryLEVERKUSEN, GERMANY: The bowstring is drawn back, the bow arches under the tension and the arrow speeds to the target. Archery is a sport that’s all about precision, which is why bow and arrow technology is continuously evolving. That also applies to the nock of an arrow – the notched tip that briefly clasps the bowstring before the tension of the drawn bow is released and the arrow takes flight. It’s the central point where tremendous energy is directly transferred to the arrow. Read More
