How to protect a FREE FALLING egg? - how to protect a free falling egg
There can be nothing in the egg fell from Bleechers football should land on somthing. So no parachute. The device can not be greater than 10 cm, but as far as I need it.
I thought, gelatin.
Ideas?
Thank you in advance.

How To Protect A Free Falling Egg How To Protect A FREE FALLING Egg?

The Land of the egg in the egg should gradually slow down (not the case that you kill it) is the sudden stop at the bottom. Jello is a good idea. If I do at the beginning of the gelatin, with lots of bubbles, would be even better. There are many other possibilities, to name but a few ... A trampoline is suitable for the task, but you have to jump carefully with the egg on the trampoline. A number of milestones that I work in one other, would be the greater the whimpiest (would be easier to stretch) the next stage with a little less, the other a little less, so you could build a series of membranes for tissue egg tear the upper layers and slower until it was not fast enough to break More. layers
Disclaimer: I have no experience with this kind of thing.
But I know that is what happens in terms of physical
Change in momentum = impulse
Change of momentum = final speed before the strike eggs times the mass of the eggs. So, if you knew the height of the stands (or could in meters) and the knowledge of the egg mass (weight in kilograms and converted), then
the dynamics of the egg = mx VF
I'm going to calculate egg mass = 0.2 kg, height 3.5 m. The terminal velocity of an egg drops of 3.5 m
vf = √ √ = 2GH (19.6) (3.5) = √ 68.6 = 8.3 m / s
Changing the retention time of an egg = (0.2) (8.3) = 1.66 NT-sec
Impetus to the cause of this change-NT = 1.66 sec
Now we have approximatelyNo way to stop making a table of the time against the force of the egg:
Impulses / time, egg stop = Force
Time Force vs peers:
0.1 s => 16.6 N
0.2 s => 8,3 N
0.3 sec => 5.5 N
0.4 s => 4.2 N
0.5 s => 3,3 N
etc.
Even if an estimate, this example shows that the extended downtime, how to get power in the egg.
Jello to do in my humble opinion, not force, the egg a lot, because the compressed but not rigid, not enough - the egg does not fall in love "with him." Water does not compress well because of it. A highly compressed material and thus reduce the force would be exerted on the egg a little bit (with a thickness of 4 to 6 inches) than air-filled foam used as bedding.
