I remember doing this project in HS but I think I won on a technicality. Either way the egg survived a two story drop and my prof. ended the contest by throwing my entry against the wall. That did it.

That is the best idea I've ever heard!

Man, When I was in Boy Scouts, we had an Island wide jamboree (O`ahu, Hawaii - Aloha Council). At the end they did the egg drop...from a helicopter 300 feet up!!

I used a small drag chute to force the package to land on a particular side (the egg was in a shoe box). The shoe box contained crumpled newspaper and super soft batting (the stuff in quilts, etc). It survived. Some guys used large parachutes, and from three-hundred feet, they didn't come close to landing in the field that we were to catch our eggs in. Lots of kids brought two eggs...if the one in their contraption broke, they would throw away the plastic bag or other container the egg was in, and just show the judges the unused egg. Trustworthy and honest little Boy Scouts...

hrmm ok instead of epoxy try that expanding foam stuff. gorilla something. use two bowls as the mold and let the foam form around the egg then glue the two halves together. hell use the epoxy too just for overkill :)

Tried that, the vertical movement is too high and it hits the ground.

elastic bands = 1
while (egg breaks) {
elastic bands ++ 1
} // while

lol, since you can't exactly put it back in the chicken...fill a bag full of boneless chicken breast and put the egg in the middle ROFL. I'm losing it.

The problem with doing something to the egg such as coating it in something, is that the egg is usually given to you just minutes before you drop it, and you must be able to pull the egg out of your device when done to succeed.

The best projects I saw were the ones that didn't try something fancy, but just secured the egg inside some absorbany material and some other material on the outside to reduce the impact... something to intentionally break or smash...

I saw a project done in 15 minutes before leaving for school succeed, while a project that was built over a span of a week fail miserably.

Parachute designs usually fail because there isn't enough time for a chute to open and fully catch the wind, and people always built the chutes too small. In relation to the size of chute needed to stop in the 2 or 3 seconds before it hits the ground, a chute would have to be pretty big.

Get a smallish box... fill it with those sealed packing bags of air, put the egg inside making sure that it can't slip out and hit the cardboard, then wrap the box very loosly in quilt stuffing (the kind that comes in sheets, not puffs) and voila. Instant success.

Success favors at-home trials, although throwing caution to the wind and finding out the hard way is a bit more fun!

Get a soccer sized nerf ball, cut it in half, cut out a two little spots for the egg, close and tape it back up. No way in hell that thing is breaking.

1. Get a 15' pipe slightly wider than an egg (transparent would be good)
2. Stand it up on one end, fill with most viscous/transclucent fluid you can find (oil/syrup)
3. Drop egg through....
4. ???
5. PROFIT!

Pantyhose FTW!

Someones got it :thumbsup:

The overall winner will be one with a low weight. Tension the pantyhose with the egg inside. Works better if the egg and pantyhose are vertical I would think. Use a streamer to keep the orientation. Shouldn't need a big box for this.

Get some small paper cups, or those little paper condiments cups. Attach the bottoms the egg, so that the opening of the cup is facing away from the egg. Completely cover the entire surface of the egg, so you have a ball of cups with an egg inside.

My son didnt inform me of this project until the night before the event. It was held at UPS. I helped him put together a box with black tape, stretch material and popcorn.

He came home with a first place medal. He beat several hundred kids with a $2.00 box of popcorn.

Surgical tubing. Can get it from any Lowes or Home Depot. Suspend the egg inside a box with the tubing and add about 1/2" of foam padding to the bottom of the box.

Wow, this is a really lame bastardization of the Rube Goldberg project that I was required to do in middle school.

Had to drop mine off a 5th floor building in 6th grade.

Took a 12" foam ball (hard foam, not soft), cut it in half, then carved room for the egg in the middle. Padded it with tissue. Sealed the foam ball shut.

I then took 6" wooden dowels and stuck them into the ball about 2 inches and glued them in place, such that the ball had spikes coming out at even intervals all across the entire thing. I then took balloons and blew them up to roughly 3/4 capacity and taped them to the end of the dowels.

The egg survived without a problem.

PEANUT BUTTER

1. Buy a new jar of peanut butter
2. Scoop out half of the jar(and save this peanut butter)
3. Place egg in middle of jar
4. Put the peanut butter you scooped out back in

I've tested it myself and it works. We had to do this for a physics project in high school and no one who used this method cracked their egg, and we were dropping them 2 stories.

for a tougher assignement, try building a beam using only balsa wood and glue capable of spanning a 12" void and supporting maximum weight at it's midpoint.


my entry supported over 160 pounds before failing. And oddly enough, had I not listened to my grad assistants advice, it would have done more.
