One way to cool an angel food cake

My cooking skills are just barely adequate to keep body and soul together, so I'm always impressed when I see clever (and logical) innovations in cooking techniques.  From a photo essay at the StarTribune:

Once an angel food is baked, it needs to cool upside-down, usually placed over a bottle. The cake clings to the bottom of the pan, so tipping it over "stretches" the cake by way of gravity, which keeps the warm, delicate crumb from collapsing on itself before it's cool.
