Polar plunges are a popular winter-related stunt, usually as a way to raise money for charity. Then there are the idiots who just jump into frozen bodies of water for fun.

Here's the most current example of the latter. A woman in Russia decided to jump into a frozen lake wearing only a bikini.

Her cannonball form was not enough to break through the ice, she did leave a huge crack though. After the video was posted online, the woman snapped a photo of her heavily bandaged ankle.
