guys I HAVE A BIG PROJECT coming up, it consists of an egg being dropped 15 ft, and it cannot break?

Eggs are very strong at their point. Weight the tip to hit at the point.  Bubble wrap the tip.  Think of an extension that is spring loaded with a weight at the end.  The balance of the container just has to protect it from bouncing.

Soak a raw egg in vinegar overnigt.  The shell on the egg will become rubberized and actually bounce.

Yes, eggs are much stronger if the force is applied from the ends than from the sides. And they are USUALLY (though not always) stronger if the force is applied from the narrow end  rather than the broad end.

The answer is an egg.

Well, while I don't want to do your physics project for you (I did this one myself so I know what works and what doesn't), the basic thing you need to consider is not protecting the shell, but reducing the IMPULSE on the shell - you know what IMPULSE is right?\n\nIMPULSE is change in momentum over time:\n\nI = (M_start - M_end) / time\n\nSo say you have a car with a momentum of 2000, and it hits a brick wall, and the collision takes 0.2 seconds.  The impulse on the car is\n\nI = (2000 - 0) / 0.2 = 10000 kg*m/s^2 (which you may recognize as a unit of force, or NEWTON)\n\nSo you might be able to find out what the impulse necessary to break an eggshell is, but I would suggest simply trying to find a method to reduce that impulse.\n\nSo you have two ways to reduce the IMPULSE on the egg:\n\n1.  Reduce the change in momentum.  How do you do that?  Momentum is mass X velocity, so since the egg's mass is probably fixed, you would want to reduce the falling velocity of the egg - think parachute or some other method of 'floating' so it doesn't fall at full speed.\n\n2.  Increase the amount of time it takes for the egg to hit the ground.  This may sound hard to do, but think about something like falling through soft cotton stuffing - the egg will move through the stuffing, slowing down as it does, and hopefully if you design it right, the egg will stop sliding through the stuffing before it hits the ground.\n\nSo there you go.  When I did this, I used the stuffing approach because our teacher prohibited any kind of floatation devices (essentially ruling out Method 1), but my egg broke because I packed the stuffing too tightly.

egg... cus jut think about it

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.

Just watched Mythbusters do exactly 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\nAny variation on this theme would work.\n\nEnjoy.

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 .

One sheet of construction paper\nOne piece of tape (around 5 inches)\n3"x3" piece of bubble wrap\nTwo six inch pieces of string\nOne sandwich bag\n\nRoll the construction paper into a cone, securing with the tape. Put the bubble wrap into this for the egg to sit on. Then attach the sandwich bag to the two pieces of string. Then attach the pieces of string to the cone of paper. The sandwich bag will act as a parachute. The cone will absorb some of the shock, as well as the bubble wrap. I cannot swear this will work, but in theory it looks like it would.

It doesn't say that the egg has to land on the concrete pavement!  Only that it is dropped 5 feet above a concrete pavement!  So I suppose you could have 5 feet of mattresses and lift the egg up about an inch or so and drop it down onto the mattresses, so that it was actually being dropped "5 feet above a concrete pavement without it breaking and without catching it"!\n\nBasically a play on words as this is:\n\nJUMP TABLES: Bet a bunch of friends that you can put three tables together, take your shoes and socks off and jump over them. They'll be anxious to bet that you can't. Take the bet money in hand then proceed to push the three tables together, take off your shoes and socks and jump over the shoes and socks. Then pick up your stuff and run as fast as you can!\n\nOr (with props the below):\n\nI would go with this: "The winning entry used "Rice Krispies" breakfast cereal in sandwich bags to enclose their egg."\n\n"Our technical support dept received the following question about dropping eggs:\n"I have been searching your web pages trying to find out how I can drop a regular raw egg off a roof without it breaking. Years ago I did this in a physics class, but cannot remember what I did. There is nothing in your web pages regarding this. My 7 yr. old grandson and I would like to do it. Could you help ?"\n\nNormally we can only answer questions related to our products, but we felt this question deserved a reply. To get a broad range of replies we asked the readers of our e-mail newsletter for help. \nSome of the answers we received\nGet an egg-eating snake, give it the egg and wait until the egg is about half way down the snake, then fit the snake with tail flights (cf a dart), then drop said snake plus egg from bridge etc.. The front of the snake will act as a crumple zone, thereby protecting the egg (makes a mess of the snake, but that is outside the parameters of the experiment) Then cut open the snake and remove the egg (snake already deceased, so this is no longer an ethical problem)\n\nIts really quite simple- can't imagine how he's forgotten that he dropped it while it was still inside the hen! Just make sure it's not a hen with clipped wings-specially if the roof is high...... \n\nTheory has it that, given sufficient height, aerodynamics will cause the egg to align itself to land on the blunter of the two ends. The egg is remarkably strong in this orientation. As long as it falls onto a reasonably forgiving surface, a lawn maybe, it won't break - sometimes!\nSafer bet is for Grandad to drop a hard boiled one and palm his stunned Grandson a raw one. \n\nI recently dropped an egg from a roof-top and was able to achieve a drop of some 15 metres without the egg breaking. How? The roof was 16 metres from the ground. It was that last metre that always did the damage.\n\nHold the egg carefully in your hands and jump off the roof. \nPut the egg in the middle of a 1 foot square styrene block. \nTake the roof off, sit it on the ground and roll the egg of the edge of the roof next to the ground. \nImmerse the egg in liquid nitrogen first \nFit the egg with a parachute. \n\nIt's really very simple, the clue is to spread all the force during the retardation phase (landing) on the COMPLETE surface of the egg. In this way, the resulting (vector) forces will be zero. In other words: The forces will "become a pressure" instead. And, since the egg may be compared to a pressure vessel (the surface is curved and can thus take really a lot of pressure before breaking) the egg will not break if you put it in strong bottle filled with water before dropping it!\n\nThis is the classical solution to the problem. I have never worked it out myself but it should work as long as the bottle itself is strong enough (do a test by dropping the bottle filled with just water before doing the test in front of an audience).\n\ncenter the egg in a nylon stocking. \nstretch

Create a enforced crate around the egg. This will require glue ( would use crazy glue) You need to create the box with enforements in the middle of the egg. That would mean in the middle of your toothpick box that you will make you will have toothpicks in the middle of the egg ( log way and short) to evenly distrube the force when the egg is dropped.\n\nFor this to be sucessful you will have to measure the egg and find the middle on the long and short side ofthe egg. after making the crate around the egg. You will need to measure the crate that you made and work your way from the middle out to put your toothpick enforcements long side and short side so the force is distribed evenly.\n\nReally It is hard to discribe. I hope you understand the instructions.

The forces are gravity down  and air drag up.\nIf you want your egg to land softly, one way is to increase its coefficient of drag -- give it a parachute.

if u r considering egg as spherical instead of oval. and surface tension is taken as T then pressure difeerence outside and inside of egg is 4T/R where  R is radius of egg.So maximum pressure it can sustain is 4T/R.\nhey,i did it.

tie a piece of string round the egg, and then measure the string
