E-Cigarettes are allowed in your carry-on, and when your bag goes through the scanner they don't really match up people with bags..unless there is an issue. So as long as nothing else in the bag causes them an alert, they probably won't even care. But IF something in your bag causes them to take a second look, when it is opened they may inquire about the E-Cigarette.
Since that is still classified as a tobacco product, this may cause you issues because you are 16. At the very least your parents may see it in your bag and ask you some questions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
