In summary, the conversation revolves around finding a way to protect an egg from breaking when dropped from a height of 20ft in a container no larger than 10cm x 10cm x 10cm. Different ideas are suggested, such as using a two-part shell, a steel cage filled with plasticene clay, or Silly Putty. Another suggestion is to use a suspension system made with high strength latex tubing. Some also consider using a helium balloon to partially support the weight of the egg.

Dropping an egg without breaking...

So I have to make a container no larger than 10cm x 10cm x 10cm.

An egg has to be placed inside the container and dropped from a height of 20ft, and the object is for the egg to survive the fall and not break.

This is a competition, and points are awarded for
1) The egg not breaking
2) The smaller the volume and mass of the object gets more points.
3) The time it takes someone to "load" the egg into the box needs to be minimized for more points.

Other than that, anything goes. I'm trying to make something light that will absorb enough of the shock that the egg can survive, but its not really heavy. Any ideas are welcome though :)

Maybe something that is cushy in the inner surface would do the trick?

I'm thinking the opposite.
Armour that (A) distributes the forces equally over as much of the egg's surface, (B) does not deform on impact (which again is equal distribution of forces)

What about a two-part shell that is cast with the egg inside it? Something like autobody repair resin? Use some Saran wrap so it doesn't stick to the shell and the two halves do not stick to each other, and it splits apart like a clamshell when it's cured. Drill holes and insert 1/4" steel pins to keep the two halves from slipping out of alignment. Strapping tape to hold the two halves together after you put the egg inside for the demo.

Oh, wait, do you get the actual victim egg before the competition? My scheme requires that the container is molded around the actual egg in order to obtain a perfect fit (egg-shell to armour interior). It would not work for any other egg.

Okay, plan B:
A very rigid steel cage slightly less than half-flled with plasticene clay. Push the egg into the clay so that there are no air spaces between it and the clay. Squish some more clay over the top of the egg, close the cage, and drop. The steel shel prevents deformation of the overall device, and the clay gives the equal distribution of force.

Plan C
Maybe Silly Putty, just on it's own, no steel cage. Maybe an inch thick all over. It has strange properties when it's suddenly subjected to tension or pressure, as if it suddenly goes rigid for a split second. It'll probably bounce like crazy, but so what? If it survives the first hit, it should survive the bounces.

One clever alternative to the typical foam filled box is a suspension system inside a frame. You make an egg "hammock", that surrounds the egg. The suspension system is made with high strength latex tubing, strong enough to keep the egg from reaching the perimeter of the frame. The frame can be something fairly solid. However, at 10cm per side, the foam inside a box concept is going to be hard to beat. Also thinking outside the box, how large would a helium balloon have to be to support or partially support the weight of an egg?

1. How can I drop an egg without breaking it?

There are a few different techniques you can try to drop an egg without breaking it. One method is to wrap the egg in a soft material, like bubble wrap or a cloth, before dropping it. Another approach is to place the egg in a container filled with a shock-absorbing substance, such as rice or flour. You can also try lowering the egg slowly using a string or parachute.

2. Why do eggs break when dropped from a height?

Eggs break when dropped from a height due to the force of impact. When an egg hits a hard surface, the force of its momentum is absorbed by the shell, causing it to crack or break. The higher the drop, the greater the force of impact, and the more likely the egg is to break.

3. Is it possible to drop an egg from any height without breaking it?

No, there is a limit to the height from which an egg can be dropped without breaking. As mentioned previously, the higher the drop, the greater the force of impact, and eventually, the impact will be too great for the egg to withstand. However, with careful techniques and materials, you can increase the height from which an egg can be dropped without breaking.

4. Does the angle at which the egg is dropped affect its chances of breaking?

Yes, the angle at which the egg is dropped can greatly impact its chances of breaking. An egg dropped from a vertical position will experience the full force of impact, making it more likely to break. However, dropping the egg at an angle can distribute the force of impact more evenly, reducing the chances of it breaking.

5. Can dropping an egg from a higher height increase its chances of survival?

Yes, dropping an egg from a higher height can increase its chances of survival. As the egg falls, it accelerates due to gravity, which means it will reach a higher speed the longer it falls. This allows more time for the egg to reach terminal velocity, where the force of air resistance equals the force of gravity. At this point, the egg will experience less force of impact upon hitting the ground, reducing the chances of it breaking. However, this method may not always be successful, and careful techniques should still be used when dropping an egg from any height.
