Can you fly like a penguin?
On land, penguins are known and loved for their clumsy waddles – but when it comes to swimming, they gracefully “fly” through the water.
Penguin wings are actually paddle-like flippers used for swimming. The motion of the flippers resembles the wing movements of flying birds, giving penguins the appearance of flying through water. The wing and breast muscles are well developed, to propel penguins through water - a medium much denser than air.
Even if you can’t get to a swimming pool, you can practice those flipper movements at home. Stand with your legs apart and stretch your arms out, before raising and lowering them just like a penguin. See how tired you are after 30 goes!
