What are the bubbles on the surface of cooking bacon?

Question

As you can see in the picture, this bacon is just about ready to be removed from the heat.

bubbly bacon

Just what are those bubbles/foam(?) on the surface of the bacon?

Note: this is fresh bacon from a butcher-- not processed or packaged-- if that makes a difference.

I'm pretty sure that's just steam and hot air bubbling in the layer of fat/grease that's all over the bacon.

yep it's boiling water, and the oil in the pan is rendered fat. the same way whale blubber was rendered into lamp oil. Just an interesting factotem
