Egg-Drop help!

Well, our school has a science fair, and I am supposed to design a device that I can put an egg inside and drop it at 4 stories high and not let it break...

-We can use anything, just as long as it is pretty light.
-The whole device must fit it a waste-basket (About the size of a cube made up of A4 papers.)
-No parachutes, wings, or other devices that slow the device's fall is allowed.

I am pretty much clueless...any help here? I need this done in 3 days :(.

Thanks.

The easiest form is a snug block of styrofoam. Not the bubbled polystyrene beads you can normally find, but the kind that looks like bubble wrap if it was shrunk down a couple of dozen times. nice, tight wrapping is a must. I got a four inch ball dropped 10 stories without breaking. Bigger balls of foam=higher drops.

Build a small cardboard/paper box and fill it with half inflated baloons. Put your egg inside and bingo!

Boil the egg.
Can't...forgot to say that. Raw fresh egg is used.

Yeah, I've been trying to put airbags, but I think that they are a bit too hard on the egg, considering that it's going to drop 40 feet... Calculate the impact.

Ok, build a small cradle for the egg, and suspend it inside a box using elastic bands.

Edit : Alternativly...

Learn the slight-of-hand magic tricks. Pretend to place the egg in the box and the pretend to remove the egg at the bottom. :lol:

Lol, the device has to be easy for the judges to remove the eggs from...

Worth a try though ;)

EDIT: More ideas please!

You need a cube-like box. it helps to cut some of the face out (only enough so the edges and whatnot are still strong)

with a smaller box suspended inside by tight rubber bands


put the egg in the smaller box, throw the bigger box as high as you possibly can, the egg will never break

edit: knightfall beat me to it.

Stuffing from a stuffed animal (or the animal itself if you can find a sufficiently cute one) surrounded by tightly packed bubblewrap surrounded by styrofoam surrounded by rubber.

I would use a cube of foam. Cut it in half and carve out a little section just big enough for the egg. Then when you get your egg, put it in one half, place the other half on top and tape it together. Keep in mind the more your box weighs, the faster it will fall, and thus it will experience a harder impact.

I think, if you make one panel of the cube (the bottom one, itll be heavier) hard on the outside, and padded on the inside with something like really soft rubber, tape the egg to the upper panel, and make the side panels flexable, the impact should be absorved mostly by the bottom panel, and the flexable side panels will bend outward. The padding will take out the rest of the impact.

as KnightFall said build a cradle for the egg. that way the egg will take a lot less damage

I did that project in the science fair as well. I put the egg in pre-shaped bubble wrap(so it's easy to remove, and then two pieces of foam which I held together with a big piece of tape. Also, I got extra credit for the project because mine was so light:D!

Ohh..you could also use the kind of foamy green thing which substitutes for soil. The stuff you can grow plants in for a while. Shave it with a knife so it's about 2cm thick and hugs the egg snuggly in place. That's VERY effective and light as well.

Whatever you do, make sure the egg is held snuggly and won't move much.

Good luck

Yeah, and you might also want to get a large wing of cardboard to glide down.

"-No parachutes, wings, or other devices that slow the device's fall is allowed."

One of the rules. Otherwise, it's a great idea.
 
I did this successfully when I was in 5th grade off of a 6-story building.

Here's what I did:

Took a ball of styrofoam about a foot across. I cut it in half, and carved out a hollow spot in the middle for the egg (and duct taped the thing shut). I then took dowels (thin, small sticks) and embedded them in the outside of the styrofoam sticking outward, ensuring they didn't come closer than at least an inch of the egg, ideally more. They were sticking out of the ball about another foot, and attached with glue. To the end of each of these (it looked like a giant ball of spikes at this point), I attached inflated balloons.

The balloons were actually enough to keep the thing from dropping like a rock (an unintended consequence, which was not counted by my teacher as against the similar rules we had to follow), and when it hit the ground, it bounced without a problem. Didn't even break a balloon.

PS--your teacher isn't Mr. Piper by any chance, is it?
