Egg drop Contest- Help Please!!
 
I know. Another egg drop contest. But I would really appreciate any help anyone could give me. Thank you in advance.

First off, I have material restrictions. I can not use any sponges (or sponge like material), manufactured boxes, manufactured stuffed animals/toys, styrofoam and foam padding.

I also have a size and weight restriction. The object cannot be bigger than 35cm x 35cm x 35cm. If the vehicle has a parachute, the parachute must fit within these restrictions. And it can not weigh more than 350 grams.

And lastly, the contraption must hold TWO eggs, and must be able to withstand numberous drops (i.e. it will be dropped from 1 m, 1.5m, 2.5m, 4m, and from the roof of my school. Between each drop height I am not able to fix or repair anything on my contraption. The vehicle might also be thrown across the room, or flipped upside down, while falling).

Now, does anyone have ANY ideas at all?

Thanks,
Cassandra

well i found the long skinny balloons you use to make party animals work as sweet cushioning. i did it with air. try with helium.

Thanks for your help, both of you.

I check out those links, but most of the other projects are just for 1 egg, and have different material restrictions and whatnot than me. Like for example, I can't exactly use the cone idea, as it will just crumble after the first drop.

Thanks for the idea about the balloons. I will be sure to try that.

Well, I thought there were enough discussions on this already, but apparantly your project is different enough to warrant another one.

I'm kind of thinking if you could somehow suspend them in the middle of something like a small beach ball. But I don't know how to open a beachball and still close it where it still holds air.

Does the parachute have to fit within the size restrictions even when it is deployed or only when it is stowed?

It must fit within the restrictions when it is fully extended.

I've attempted to build one already - consisting of popsicle sticks, elastic bands, and these cup holder things. Only problem is, was that it was way too heavy for the parachute to have any sort of affect on the contraption.

Thanks for all of your help already :)

Ive heard that the best padding material for this is lawn clippings - grass from your back yard.

maybe thats why some many species of birds make their nests out of grass?

I know that in my class people used a tin can full of jello, but that was for one egg, maybe something along the same lines filled with jello?

I was thinking something along those lines too, but the only problem there is weight.

EDIT: Uh, how much does 350 grams weight in ounzes and pounds for those of us who are metrically challenged?

Thank you Ken! I'm not sure what it means by manufactured box but if you can use a cardboard box for example, or any container, (probably the bigger the better) fill it to the brim with grass clippings (assuming they are still available where you live). Then put the two eggs as close to the center as you can, without them being two close to one another. Have Fun!

i htink i did my factor labeling right.....

Nope, there are 16 ounces in a pound, not 12.

(350gr/454grperlb)(16ozperlb) = 12.33 oz

unless you are measuring precious metals, then its 12 oz to a pound (which is why a pound of feathers weighs more than a pound of gold)

isnt the SI system wonderfull?

What my teacher means by "manufactured boxes" is that you can't use an already made box. You can make a box, out of whatever you'd like, but it can not be a box that you buy in stores or whatever.

Thanks again.

What does everyone think about a pyramid shaped thing?
