SOUTH POLE -- Saturday might have been the first day of summer, but it was the winter solstice in Antarctica.
Researchers at the South Pole celebrated by taking a dip in the pool.
The scientists at the Davis Station had to saw through a yard of ice, then they set up some fake palm trees and jumped in.
The water is said to be about 2 degrees, but that's pretty balmy considering the air temperature was about minus-30.
The polar plunge is a big deal at the station because it marks the halfway point of the scientists' stay on the continent.
