Beakman's World: String and Ice Challenge
00:10:45 - 00:13:28
Chemistry → Physical Properties of Matter → Freezing Point
Lester is challenged to use only a piece of string to pick up a piece of ice without touching it. USing salt, he sprinkles it on the ice and wets the string and sits it on the ice. After about 2 minutes, the string is now frozen to the ice and it can be picked up. This is because salt lowered the freezing point of water and now the water on the string can freeze to the ice cube.
