Why can’t you take a bottle of water through security?
Even the best people at airplane trivia might not know why bottled water is such a no-no in security lines. You can’t take a bottle of water through security because it causes both safety and time issues. While TSA security scanners are advanced, they have trouble telling a full bottle of water apart from a bottle of chemicals. TSA allows liquids in small doses, but they have to go through separate from your carry-on luggage.
