Ok teen's love theme's especially girls. Try doing a 50's theme, with martini's (not real ones of course) but maybe some non alcoholic drinks with a olive, make them feel grown up. Make alot of little appetizer's.
Around 12am pass around champagne glasses with sprite and strawberries. Make sure everybody dresses up.
Depends on what age the teens are, as 13-15 are going to want something very different from 16-18. However both age groups will love fireworks. Keep in mind that teenagers can keep themselves fairly entertained so don't feel the need to provide games and activities for them to do.
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.
