Why can I touch tin foil the moment it's removed from the oven?

It doesn't seem to get hot when shoved in a 200°C oven while covering a tray and food which do get hot. What gives?

It does get hot from being in the oven, and aluminum (not actually tin) is very efficient at transferring heat. The thing is, it's so thin that there's just not that much total heat there to be transferred to anything else. It cools pretty quickly on contact with air when you remove it from the oven, and even faster if you touch it with your skin.
