Everything you need to do it in style. Or fail spectacularly...

Our teacher, probably wisely, didn't allow us to shoot ours off.

yeah, same thing in my 11th grade physics. My thinking was not to absorb the impact, but disperse it, since that energy has to go somewhere. So I dug a hole in the middle of a watermelon and placed the egg inside. I put the cap back on and heaved it off the roof. It hits the ground, exploded watermelon hits everything within 20 yards, and on the ground is a flattened, cracked section of watermelon--just rind, the meat had blown off--with an uncracked egg sitting in the middle.
It wasn't as sophisticated or elegant or high-tech as some others, but it worked.

LOL, I wish I had pictures of my overthetop Egg Drop Project from the fifth grade.

Basically, try getting a large hunk of foam, cut it in half, then hollow out enough space for the egg. basically it would be like having a hard boiled egg cut in half without the egg yolks.

*edit, vagarach beat me to it. I did one better though, I glued strips of light cardboard to the outside of the styrofoam sphere which was carved into a teardrop shape. The bottom was weighted with a bean bag. The egg drop project called for fastest drop time, closest to target area, and egg surviving.

Thanks Edwood, do you think I could fit 3 eggs in a foam with the largest dimension being 25cm?

I don't think that the watermelon would work for 3 eggs. Plus I don't want to clean watermelon. Such slothfulness is what plagues me from getting a perfect gpa.

i seriously had the BEST EVAR egg drop project, seriously!

i lined a small container with a thin foam/bubble wrap combo, half-filled it with clear-gel hand soap, and dipped the egg, wrapped in bubble wrap, inside

to the bottom of the container, i tied 4 ENORMOUS water balloons (tsk....some of you have forgotten highschool physics already eh? g=9.8m/s2, for ALL objects w/o considering air resistance)

anyways....dropped it from 6 stories, created a HUGEASS crater (it was a foot deep in hardpacked soil) and the egg was unscathed


theory is that the enormous upward spray/blast/wave of water would slow down the tiny light container enough before impact to survive



sooo.....not only did the egg survive, but cool as hell to watch and highly repeatable too

Wanna bet? I shot one of those rockets up about 800 feet when I was younger which came back down in a parachute without a scratch on it.

Just a search of 'egg drop' on Google will even show you the majority of the successful ones all use parachutes and rightly so, this is a no brainer... a guy jumps out of a plane he uses a parachute, not Jello.

Would be a tight fit, but make sure the eggs are not touching each other. Perhaps sandwhich them side by side. The best way is to orient the eggs so that when the whole thing hits the ground, the eggs are standing up. Eggs are much more vulnerable on their side.

When I did the Egg drop thing way back in the fifth grade, the teacher added a target area and drop speed as variables that made parachutes a bad idea.

How about using half a 25cm stryofoam sphere as an aeroshell? 3 eggs placed vertically in individually hollowed out area near the center. No sure on the balance or if the fall is long enough for the shell to right itself.

I'll take the bet. You attach up to 1kg of parachute to an egg, and drop it from 20ft. If it survives, I'll make you breakfast with the eggs. Mathamaticly possible, but practically very difficult. Of course, if you're talking about plastic nosecones, you can drop those from a mile up and they still won't take a scratch.

When I jumped out of planes, para-foil chutes still only decreased vertical speed to about 10-20mph. (You flare into the wind right before landing to scrub off the remaining speed) Hitting something at 10mph (around 14ft/sec) is still pretty painful.

I remember doing this in highschool as well. We werent allowed to coat the egg with anything, so I just wrapped mine in a ton of bubble wrap. Survived without a hitch.

One of my classmates put his inside a foam ball, as was mentioned above, but also stuck a ton of straws onto the foam ball. His fell slower than the others, and on impact the straws slowed the ball before it hit.

The best one involved a classmate who actually forgot his project at home. Took out his lunch, cooked one of those styrofoam cups of ramen, drained the broth and put the egg in there. Taped it up and threw it off the stadium. It survived!
