H999 contest

I thought we had to keep from scrambling it as well?

Again using a centrifuge as an example where 25K gees might be obtained, the only stuff that migrates is not at neutral density. What is interesting IMO is that using sugar, salt whatever you can create a gradient within the vial and all ends up at at rest where it is neutral. At first, I was concerned that even if the egg remained static, the yolk might not. Not sure how well matched the densities of the yolk and white are. So I got an egg from the fridge and opened a hole in the bottom–guess what a decent liner of white but the yolk is nowhere near the middle.
Food for thought?

you all are funny!! i think we need to try to have this mythbusted 10 dollars a shot ante or something.
the thing with oil is if the egg is on top of the oil. this kinda remindes me a raft in a swimming pool it floats great, til some 200pound guy jumps in the center of it and the whole thing sinks to the bottom momentarily then the raft does a bouy kinda thing and flips out from underneath. regardless that amount is not a lot of force on the raft, but it still hits the bottom in my opinion.
Have you seen the commercial where the pitcher throughs a good 30mph egg at the tempur pedic? the stupid thing doesnt break.
oil shock absorber pistons hit bottom all the time… thats why they make a thing called a bump stop so you dont damage your shock absorbers
when you hit a pot hole doing about 60 mph.

i wonder if your threw an egg at a vat of oil at 30 mph if it would break?

[Chris LaPanse]

What I’m arguing is not analogous to any of those situations.

What I’m saying is that if you had a ball with a fluid of exactly identical density to an egg, with an egg suspended in the middle, if you dropped this say 50 feet onto concrete, the egg would be untouched (though the yolk may be scrambled, and all this is assuming the container with the fluid and egg does not break). The requirement for this to happen is that BOTH the fluid AND the egg must undergo acceleration. If the egg hits a stationary vat of fluid at high speed, it will likely break. That is the key for all of this to work.

One key principle for this is the principle that from any one point inside an accelerating vehicle, the acceleration forces are indistinguishable from gravity (of a comparable magnitude). Although the egg feels a strong pull downwards, so does the liquid surrounding it. As long as the egg and the liquid are of equal density, there will be zero net force on the egg from a reference frame where the container (the rocket) is stationary. It will simply remain where it is. The only potential problem that I can see is that in this process, the pressure on the egg would be increased substantially (inward pressure, not in any specific direction). If the egg was only slightly compressible, at these high g-loads, it could crack simply from this pressure. Some quick calculations put a 115 g acceleration pressure at about 17psi. The egg would have to take this (egg hyperbaric chamber tests anyone?), but would feel no other force. No shock absorption system can make the claim that the egg would feel zero net force in the reference frame of the rocket). This is why the fluid method would be the best if it could be perfected.

As for the yolk not breaking, that cannot really be influenced from the outside. The 115G acceleration would be identical to the effects of a centrifuge, and even a slight differential in density between the yolk and the white would cause some significant bouncing around during the actual flight. Basically, preventing the egg from breaking should be the goal, as it is doable, while preventing the yolk from breaking is basically impossible with high enough acceleration.

oh the technicalities…. and the thought process…
maybe we just K.I.S.S. Keep it simple sweetheart
The Contest:

1. max alt Eggloft
2. 1 large grade A non cooked egg
3. H999 motor
4. safe recovery of the egg (no cracks or loss of egg matter)
5. altimeter checked and recorded
6. Contest only to be performed at MHM and/or OF on SAT of those events
same requirements of the SSSS must recover by the end of waiver.
7. testing can be preformed anytime of the year in according to NCR waivers and certification levels of the contestant (i.e. not allowed to compete if not certified level 1 or higher by NAR or TRA)

sounds like a idea to me… then all us can test our theories and see
who’s egg can take 115g’s of force
does this sound feesable? or a baseline idea? maybe more do this like the beer boost contest?

also chris what if your used egg albumen and yolk as your medium of suspension wouldnt the density of fluid inside be the same as the outside of the egg? also the fresher the egg the stronger the yolk sac wall is less chance of yolk break… but that should not be included in contest( yolk break) eggs internals are too unpredictable IMO some eggs have double yolks, some break no matter what we do

[denverdoc]

Doc S,

Sounds good to me. And minus the small amount of shell of higher density, the density would be the same obviously. Plus we have breakast for sunday. I still vote for some incentive for intact yolks(maybe a 10 percnt bonus in measured altitude?)–if these were astronauts, what good would it have intact bodies and scrambled brains?

[Chris LaPanse]

The problem is that the bonus applied there is pure luck. I think it should be simply that the egg is intact (and as far as astronauts go, that’s the problem with extreme g-forces. In fluid suspension, they can take quite high loads, but the internal organs start to shift around).

As for using the egg internals as a medium of suspension – that is a good idea, although I’d have to see about certain other possibilities first. Certainly would make things interesting…

[denverdoc]

CJL,

Why would you assume its pure luck? If anything is pure luck its this years SSS as regards the cato issue. Granted you may pick a bad egg, but hey I cook literally hundreds of eggs a year when I’m on a protein diet–in my entire life I’ve seen maybe 2 twins, a few fertilized eggs, and not a single broken yolk, unless I broke it. Methinks you guys are clucking up the wrong tree ;-D
John S

[Chris LaPanse]

By pure luck, I mean that some egg yolks are bound to be stronger than others, and that there is no real way to test whether any particular egg will stand up to it.

[denverdoc]

Apart from the fact that you have some reason to believe some would-be chickens are stronger than others? Ok we buy the expensive eggs from the organic, free to roam about and be chickens on hormone free diets, are there any other objections? 😉
JS

[Chris LaPanse]

Heh…

I’m not saying that has anything to do with it – I’m saying there will be some natural variations because NOTHING in nature comes out identical every time. Some eggs will have larger yolks, some smaller, some weaker, some stronger, etc. I’m saying it introduces an element of randomness in an otherwise skill-based contest.
