I'm doing an egg drop project in science. Its pass or fail based on if the egg breaks.

Additions to the egg must be under 75 grams. Thats the only rule.

Submit yo designs.

5 Bucks goes to whoever's design I pick so long as the egg doesn't break.

I didn't have a weight limit on mine so I'm not sure what it ended up at for weight but I did something like this made out of cardboard and ducttape:



padded on the inside, one side opened and stayed shut with velcro (tape works fine), with string and a lightweight parachute attached at the top to slow the fall. Egg didn't break, but you'd have to work with it to get it down to that weight.



edit: I read the OP as something to add to the egg, if it can be a landing platform then things change a bit.

[midnghtraver]

Landing thing works too. So long as its a combined weight under 75 grams.

[justin_ator]

biggest thing with landing pads is dealing with not missing. I saw wayyyyy too many eggs break with people barely missing the landing pad.

lulz, when I did this project in physics, we were only allowed 1 straw, 10 pins, 1 piece of paper and 5 inches of tape. Not even kidding. 75 grams would have been a luxury.

worked like a charm when I did my egg drop. Use a bike pump or something to inflate the bags if air leaks out.

okay I can't say my design worked on the first drop, but it did on the second. It was from probably 45 feet onto a gym floor. I would assume the higher the drop is from the better chance the egg stands (as the parachute has more time to open and create a counterforce to gravity.) A parachute is pretty much necessary as I have seen many many designs fail because of mid-air rotation (i.e. not landing like it was supposed to land [which is also why justin-ator's design wouldn't work as the only way to make sure it lands correctly is with a weight, and it's to my understanding that you're trying to avoid weight like the plague]). A parachute pretty much guarantees that your device will land within 45° of it's intended landing position, that is unless your parachute fails, in which case.. you fail.

Don't get overconfident in your design, as two kids in my class had some acclaimed super foam that would allegedly succeed without fail. It failed tremendously of course.

My friend literally ripped memory foam off of an old bed, taped it together with duct tape on all sides, dropped it from the top of a 10 story building, and it didn't break. LOL

All you need is a piece of memory foam big enough to hold the egg and duct tape. :P Good luck with your project either way.
I did make a parachute out of a Pringles cup, punched holes in the side of it, filled it with cotton balls (place egg halfway through), and used a plastic bag as a parachute. But I don't have either of the pictures from the dropping so these are just ideas.

I did this. It worked.

My favorite that I've seen was a cardboard cylinder with a condom holding the egg inside. Had like rice krispies cereal or something above and below the egg (inside the condom). Can't remember if it broke on the highest drop or not, but I know it made it there.

me too

[Gravity Kitten]

doing the same thing this year actually

my method:
i'm just gonna raise a few chickens in the mean time and inject them all with steroids, thus providing super eggs

probably going to pray alot too

cause that helps you know

[midnghtraver]

I was thinking of soaking my egg in vinegar for a couple days before the experiment so it gets all soft and doesn't break but I'm not sure if my teacher would be cool with that.

[darkshark]

Build any design you want and offset the additional weight with helium.

[iironiic]

You essentially want to use material that maximizes the impact time between the egg and the surface. I forgot what the technical name is, but at least I remembered some physics since I took the class about 3-4 years ago! (:

[justin_ator]

rushy, it doesn't matter what side it lands on because the whole thing is padded inside for one, and second it has a parachute as well.

EDIT: I actually used this same design when we did bottle rocket launches with eggs in physics, I got to do three launches with one egg. First one worked like a charm, parachute and all, second one the parachute got stuck and didn't deploy but the egg lived somehow, and the third...lmao it failed to deploy and it came down and hit the edge of the bleachers, crushed the egg and got it everywhere rofl.

memory foam would be heavier than 75g
