Drop an egg from forty feet w/o breaking it?

I need to drop an egg from forty feet and need to build a structure so it won't break. I can ONLY use 15 popsicle sticks, 15 straws, 15 coffee stirrers, 5 rubber bands, 1 meter of tape, 1 meter of string and elmers glue.
oh and i can't build a parachute either

Construct a container designed to catch and protect an egg dropped from varying heights (2-5 stories!). Some competitions are judged by the bounding cube volume of your container, others by the maximum height of the container. You can use basically any materials, although some competitions stipulate that wet or liquid materials are illegal. Obviously, it is essential that you don't miss. Hence, teams are allowed to use a plumb bob attached to a frame to position their containers, and glue a thread harness to the egg. The harness would be hung from the same hook as the plumb line, and the thread burned through to release the egg straight down.

My device was a small box filled with pieces of cellulose sponge and tissue paper, with a cardboard trap on top to keep the egg from bouncing out. It worked pretty well but wasn't as small as it could be. This event has been pretty much solved, since people have discovered certain materials can cushion an egg very well even though they are less than 1/2 inch thick. These include: hard modeling Styrofoam (the real hard stuff that makes crunchy indentations, not just the stuff that is used for shipping) and alternating layers of rubber sheeting and bubble wrap. You may not believe me, but I've seen it with my own eyes. Astonishing really, that a 1/2 inch thick piece of styrofoam can cushion an egg dropped from 5 stories. Of course the egg bounces crazily; I've seen people use strips of duct tape, sticky-side up to keep it from bouncing around. At the state meet, somebody used peanut butter and would have won hands down, except that peanut butter was ruled to be a liquid and the team was disqualified.
Someone else this this device:
"i did mine with a soda can and it survived a drop of about 65 feet from some football bleachers. AND we had the requirement that the egg had to be at least half visible from the casing.
i took the soda can and very carefully cut off the top. I then placed a good deal of copper bb's in the bottom of the can so that it would always be bottom heavy (this is because due to the exposure rule my egg actually extended above the top opening of the can). on top of the bb's i put ALOT of cotton balls very loosely packed to form a deep nest for the egg: remember, you want to make the stopping distance of the egg as long as possible... pack your padding too tight and impact'll crush the egg, pack it too loose and there's not enough to stop the egg from hitting the bb's, test it out before the actual trial.

next i sat the egg on top of the cotton and then used thin strips of duck tape to form a cross over the top of the egg, securing it to the open top of the can. the cool part is that you can see at least half of the egg this way, and people think it'll fail since the egg sits partially above the can (you don't want it to sit too high though, only about a third of the egg's height should be exposed above the top of the can). just make sure you put enough bb's so that even if you throw the can up upside down it'll come down bb side first."
Combine this with an large air bag and NASA will hire you
