quick question for anyone that can really help. im going to cancun for spring break and i am flying there, i need to know if the bottles not amps will get through metal detectors. this my be a stupid question but the upper area of most bottles look like they have a circular metal surrounding where you extract. will this area of the bottle cause the metal detecors to go off. i need to some quality info, and what might be other ways to get stuff back.
