How come alumnum foil doesn't get hot in the oven?

It does. It cools very quickly because it's so thin. Lots of surface area to radiate heat + low mass (very little thickness) means it doesn't stay hot for long.

I doubt it cools down from 450 degrees to room temparature in a matter of 5 seconds...

lol at aluminum not getting hot.If that was the case NASA could save a bunch of dough by just wrapping the space shuttle in tinfoil.

Who wouldn't if they could?
 
There's more to it than the rate at which it cools. NOT because it cools down quickly..

But rather, because it has a low specific heat. Thin aluminum foil simply doesn't hold enough heat at 450 degrees (F) to burn you.

Space shuttle tiles: Hold a LOT of heat, cool very slowly, but won't burn you.
Steam sprayed on you: can start out at well above 212 F, but cools very quickly to 212 when it's sprayed on skin. Burns severely.
