Flight delay survival kit

We are spending this weekend in Stavanger to participate in a major family gathering, which is always nice. Our flight out of Oslo was seriously delayed, and we ended up killing a lot of time at the airport, not so nice. I spotted this young boy close to where we were sitting playing with his Lego and stuff for what seemed like hours. Very busy and obviously having a great time not giving flight delays a lot of thought. Now I know what to bring the next time I fly somewhere :-).
