   Dr. Nina Byte · Tech & Science CorrespondentChip asked me how penguins stay warm. Turns out it's basically just layering and teamwork.

   Dr. Nina Byte · Tech & Science CorrespondentStep one. Emperor penguins live in Antarctica, the coldest place on Earth.

   Chip Darnell · U.S. News AnchorLove that. So it's like being stuck outside in a blizzard with no escape plan.

   Dr. Nina Byte · Tech & Science CorrespondentStep three. In big storms, they squeeze together in a huddle. Per Wikipedia, they take turns on the outside.

10. 

    Dr. Nina Byte · Tech & Science CorrespondentNo wristbands. No Randy. They just take turns, Chip.

    Chip Darnell · U.S. News AnchorOkay, but who keeps the egg warm?

12. 

    Dr. Nina Byte · Tech & Science CorrespondentThat's the right question. The dads. Male emperor penguins balance the egg on their feet under loose skin for around sixty-five to seventy-five days.

    Chip Darnell · U.S. News AnchorSo the dad's the ring toss guy, holding the prize for two months. Does he get a wristband?
