Can Katie Ledecky Really Balance A Glass Of Milk On Her Head While Swimming??

She swims the entire length of a swimming pool with a glass of chocolate milk on her head and doesn't spill a DROP.

I mean, we all know that she's good, but we didn't realize that she was THAT good.

Seriously, how can you swim and keep your head that still?

The next question is, of course, why did she do it? I mean, sure, just because she can is a good enough reason, but Yahoo! Sports reveals that there was another reason behind it. It's actually going to be part of a new "Got Milk?" campaign. But, that doesn't change the fact that she did it and it was freaking awesome.
