Watch Katie Ledecky swim a whole pool length balancing a cup of milk on her head

AMAZING.

Katie Ledecky is a rockstar in the pool and famous not just for usually beating her opponents but also for the way she absolutely dominates them, sometimes finishing a race several body lengths ahead of second place.

But as it turns out, the five-time Olympic gold medalist can perform at least one truly astonishing trick in the pool too.

Monday on Instagram, Ledecky posted a video of herself swimming one length of the pool (likely 50 meters but possibly 50 yards). No big deal, right?

The catch was she had a cup of chocolate milk balancing on her head, and she made it the whole way without it falling off. It seems ridiculously challenging, but Ledecky, of course, somehow made it look super easy.

Even if this is a new Got Milk? ad for the 23-year-old distance swimmer, it’s still remarkably impressive. She made it all the way to the other end — with the help of a snorkel, a common training tool — and took a sip while resting on the wall.

In a video posted to her Instagram story, Ledecky laughed while explaining: “I was bracing my core so hard because I can’t move. I have to stay still.

We’re impressed.
