Before 2006, you could bring a liter of sunscreen and a gallon of mouthwash through security. No worries. Then came the 2006 Transatlantic Aircraft Plot.
A group of terrorists planned to smuggle liquid explosives disguised as soft drinks. They’d assemble bombs mid-flight using peroxide and other goo. This was nearly real.
The plan failed, but it freaked out the entire world. Overnight, the “liquids ban” was born. Your 4-ounce water bottle became a weapon of mass disruption.
Quirky Rule #1: The Gel Exception
Not all gels are created equal. You can bring gel inserts for your shoes—those squishy foot helpers—without a limit. Why? Because they’re attached to your feet.
But a $100 jar of face cream? Nope. That’s a liquid. Unless it’s a solid stick deodorant, which is fine. The line between solid and liquid is hilariously blurry.
And peanut butter? Officially a liquid. So is yogurt, jelly, and even nutella. Sorry, pre-flight pancake breakfast.
