What is a good birthday idea for being on a plane?

I'm flying overnight this summer to Israel and it's my friends birthday while we are on the plane.

I want to do something special for her and do something that really impresses her, if you know what I mean.



Any ideas? I'm open to a broad range of ideas..



More general things tho.



Thanks in advance.What is a good birthday idea for being on a plane?Give her an ipod to use on the flight, a book that you know she'll like, a small gift box filled with things she can use on the trip, a fancy sleep mask, a cupcake with an unlit candle.
