Why can I take tin foil out of a 350 degree oven with my bare hands?

Aluminum foil is incredibly thin material, so it really can't hold a lot of heat. This is because it has *a lot* of surface area compared to its mass, which means it has many many places through which it can lose heat, but its low mass means it cannot store much heat. (Aluminum also has a somewhat low heat capacity - about 1/4th that of water - which means that for a given number of grams, water can store more than 4 times as much thermal energy as aluminum can.)

To reiterate: it holds very little heat, and the heat it does hold it's able to lose very quickly. So quickly, in fact, that even though it's touching your nice, hot, freshly baked potato only 2 inches from where you touch the foil to pick it up, all the heat that it picks up from the potato is summarily lost in the short distance between the potato and your tender little fingers.
