Egg drop help! In science (10 points)?

We are doing an egg drop experiment in science and we have to drop an egg in a contraption that we built from a one story building. We cannot use already made boxes, if we choose to make a box we have to build it. We can use household items. Also the contraption cannot be more then 200 grams and it has to be able to fit in a 25 by 25 box, with the lid closed. SO can you help me, because i am REALLY stumped on what i should make. the egg will be a grade A large, and we have to make the contraption before we put the egg in. SO pleaase. HELP ? Can you name something i could do .. with the materials i would need. THANKS :)
