How does tin foil in the oven not get hot?

Like I understand it’s reflecting heat, cool. But like with the direct heat when you put it in the oven, how does it not just get hotter?

It does get hot. But since it is so thin, it has very little mass and a very high surface area compared to that mass. So by the time you’ve pulled it out of the oven, it’s already cooled down quite a bit. That very low mass also means there is not much actual heat energy stored there to burn you.
