The TSA has pretty clear rules when it comes to liquids and gels in carry-on bags, but what about solid ice? Well, it turns out that ice is actually allowed in reasonable quantities, but you have to follow some guidelines. You can't just bring a big block of ice through security, that would be weird, but you can bring small amounts of ice in a sealed container.
But why would you want to bring ice through TSA in the first place? Maybe you have a favorite drink that you like to enjoy on the plane, or perhaps you need to keep some medication cool. Whatever the reason, it's nice to know that you can bring ice with you, as long as you follow the rules. It's like bringing a cool companion on your trip, get it, cool?
