Your fingers get stuck.

imageWhy is it that when you touch really cold metal, your fingers get stuck?

Answer. Posted on Thursday, January 22, 2015.

Naturally, your skin is at a higher temperature than the metal and when you touch a cold metal surface with your finger, heat rapidly flows from your finger into the metal. Metal conducts the heat well and if you touch a very cold piece of metal, the heat from your skin would be carried away very quickly, which lowers the temperature of your skin. The temperature of the surface of the skin will be lowered below the freezing point of water. The moisture from your skin would then freeze, “sticking” your skin to the metal.
