Cool Cash
Here’s an experiment you can try at home. Take three pennies. Place two of them in the freezer. When they are nice and cold, line them up on a table with the one that wasn’t chilled in the middle. So, you have one warm penny surrounded by two cold pennies. Now, using one hand, put your first finger and your third finger on the cold pennies. No surprise, they will feel cold. However, you may be surprised to find that when you touch the remaining penny, the one that wasn’t chilled, with your middle finger, it too will feel cold.
