Scientists have figured out where penguins get the air bubbles that show up right before they get out of the water!
Alright, not something I had thought to wonder about either, but it's amazing!
They trap air in their feathers right before they jump in the water. Then they dive to depths which compress the air (hunting and feeding).
When they are ready to come up, they swim rapidly to the surface and the air expands, slipping through the feathers and creating a "skin" of bubbles which reduces drag and allows them to reach speeds which send them flying out of the water!!
