Come on, no glass around the pool! If that had broken people would be invisibly shredding their feet for years.
Olympic Swimmer Does Lap While Balancing Glass Of Chocolate Milk On Her Head

This is a video of five time Olympic gold medalist swimmer Katie Ledecky swimming a lap while balancing a glass of chocolate milk on her head to participate in the TikTok Got Milk? challenge, and not the WTF World Do We Live In? challenge like you might have expected. Her technique — smooth as silk. Of course what would have happened if she had spilled that milk and contaminated the pool? I mean that’s a lot of diluted chocolate milk to drink, and I’m only one man.

Thanks to Kathy L, who agrees not using that snorkel to blow bubbles in the chocolate milk afterwards was a huge missed opportunity.
