How can drop an EGGfreefalling... in a container which can weigh no more then 600grams?

Small box with bubble wrap around the egg and plastic packing peanuts should do the job.  I had a marketing class on wrapping and we kicked it down the stairs and my egg was safe and sound.\n\nTest it at home before bringing it to class.

This can be done with a density gradient column.  It is made of 2 fluids that are carefully mixed so that the density of the mixture varies from the top of the container to the bottom.  An object will then come to rest where its density matches the mixture.  This is actually a very accurate way of determining the density of materials.  However, over time the fluids in the column mix by diffusion and will eventually cause the suspended objects to sink or float.

Eggs don't brake, they break.  \n\nMake sure it drops onto some soft foam.  Then it won't break.

crush it and put it in water

This sounds sort of like a science project our class did when I was in 8th grade.  We didn't THROW the eggs, but dropped them from the top of the football bleachers to the ground below.  Each student had to come up with their own way, and were graded according to how well they did.  If you're THROWING the egg, then my idea won't help, but if you're dropping it, it protected my egg and earned me an A+ for egg-survivibilty and creativity.\n\nI took a small container of acne wipes (like clearsil or Oxy Pads, but I used the Avon brand pads), emptied it out, and cut a hole in the lid just big enough for a cut-out from a styrofoam egg package to stick out on top.  (Just the same that ONE egg sits on.)  This made a "helmet" for my egg to poke through the top.  Then I lined the bottom of the container with fluffy cotton balls so the egg sat in there nice and cozy.  If there is room to move, it will be more likely to break.\n\nNext I filled up several ballons with helium and attached them to the container, all around in a circle so I will float down gently without spinning or turning upside down.  Can't remember how many it took, but just enough so it floats down SLOWLY, not not so many that it will float away!  I think I found out how many it took to make it float, then minus one.  On the day we dropped the eggs, mine was one of the few survivors, floating gracefully down.  When I retrieved it, I just unscrewed the lid and there was my egg, safe and sound.  :)\n\nOh, and 3 guys tried stuffing it in a pillow, but they all went SPLAT.  So that's not a good way, from what I've witnessed at least.\n\nGood luck, and I hope this helped!

The simple answer is to have a mechanism for absorbing the impact of the fall. What to build depends on what materials you are restricted to.\n\nThere are several ways to go about it. Design a super-structure (the outside part) that crumples when hit. Suspending the egg is also a great idea (as was already suggested) If you can't or don't want to use a sock or stocking, using some kind of thick substance like gelatin would work well. Parachutes also work very nicely, I've seen some cool ones that worked like helicopters, spinning to slow down the descent. If you want a better answer I suggest posting whether you are restricted to certain materials.

should weigh around 9 oz, got this at parenting.com. enjoy

Everyone must drop a egg from a height and not break the egg. All you can use is rubberbands and straws. So you cover the egg with straws (2 or 3 layers) and tie the ends with the rubberbands .

My science class did the same project a few years ago. I suggest suspending the egg within a sphere, try making wings to slow its fall. I dont think whether it is a trianlge or not will really affect its streght to much. Good luck

There are many possible implementations, but the underlying principle is the same... there are 2 strategies\n\n1) Trying to extend the eggs acceleration (reducing to 0m/s) as long as possible, so the rate of slowing down is reduced.  This reduces the force on the egg's structre.\n\n2) Trying to reinforce the structure of the egg (encasing in plastic or styrofoam or rubber) such that it can structurally survive the rapid acceleration to 0m/s upon hitting the ground, because the force on the egg is evenly distributed across it's surface.

drop a concrete block on it

Dude, if you're dropped from a roof I'd think the *last* thing you'd worry about is breaking an egg.  Of course, that's just my opinion; I've never been dropped from a roof.

That depend upon what do you mean by float.  If you want the top of the egg to just barely stick out of the water solution then you only need to make the water slightly more dense than the egg.\nThe density of both the yolk and white is about 1.035, but this is only 89% of the total.  Most of the remaining 11% is the shell (which is mostly calcium carbonate) with a density of about 2.8 grams per cubic centimeter.  If you do the math and then convert into regular measurements, it comes out about 4 tablespoons per cup of water to get an egg to just float.  Adding more salt will make the egg float higher.  The upper limit of salt addition seems to be about 7 ½ or 8 tablespoons (no more salt will dissolve unless you heat the water).

I watched Mythbusters do this.\n\nIf you dismiss Jamie's rule-bending by lowering it with string, Adam managed it by making a cone out of paper, weighting the point and putting the egg between two inflated rubber gloves.\n\nThe nose crumpled dissipating the energy with the gloves cushioning the egg when it fell sideways.\n\n\nAny variation on this theme would work - let me know if you need more.\n\nEnjoy.

part of the trick is to have the egg land vertically because it less likely to crack at the ends; if this is not possible, try to stick with conatined (like a box) soft items, such as cloth, rubber, styrofoam (anything plyable) on top w/ support
