What are some fun things to do on a 48h Plane Ride?

Im going to Bangladesh (From Canada) and I know im going to get really bored. What are some fun things I could do? I know to bring Ipod, Camera, Binoculars, Nintendo, ETC. And my moms going to be sitting beside me, so shes the only only one I can really talk to. And I know its not 48h non-stop I think we will stop once. But that would be at night. And, HELP. I need fun things to do.
