This is such a bummer! Word has been moving quickly across the internet that the TSA does not allow you to fly with the "Thermal Detonator" Coke bottles. They are not allowed in bring them in your carry on, or your checked luggage.
TSA claims they resemble an “inert explosive”...
“Even with a normal bottle cap, this item is still considered a replica and is not allowed in carry-on or checked bags...If our officers discover a replica item during screening and believes it’s real, the item will be treated as such until advised otherwise by law enforcement.”
So sad! Be sure to get all your Instagram pics with the Coke bottles while you are in Disneyland, cause you won't be bringing them home!
