Ever wish you could bring a full water bottle through airport security? Turns out, you can—if it’s frozen solid! TSA actually lets you carry frozen liquids through the checkpoint, but there’s a catch: if it’s even a little slushy or melted, you’re back to the tiny 3.4 oz rule. Pro tip: freeze your bottle rock-solid before you go, but don’t count on it if you’re running late. Who knew?! #TravelHacks #TSA #AirportTips #Travel
