Apparently Google doesn't know either, so the question stands. How fast would you have to throw a hardboiled egg in order to shatter someone's skull? Would wind resistance prevent that velocity from even being reached? Where's Mr. Wizard when you need him!

I couldn't agree more.

I also want them to test the old elementary school myth of whether or not the food coloring in Mountain Dew and other soft drinks (Yellow 6 I think) shrinks your pecker.

Wasn't there a recent Salmonella outbreak? In that case, you can just force the person to eat a hard boiled egg.
#13
it'd have to be going pretty damn fast... but i just don't think there's enough structural integrity in an egg shell to smash a skull.

Eggshell thin

Human skull Thick (compared to eggshell)

If you had to throw it, there'd have to be an agreed on maximum speed that a human could throw the egg at. I guess you could use a major league baseball pitcher. which can reach over 100 mph i think?

I'm thinking that even at those speeds, it couldn't. So you'd have to hop the speed up and even then.. its a tough call as to whether the egg would even stay together at speeds like that.

a chicken egg? I don't think so. maybe bruising at most.

of course, you could always make them choke on it.

Salmonella is not usually deadly, and even if it was, the boiling of the egg would kill any salmonella if cooked thoroughly.

I was unable to find on average how much energy is required to cause a bone to break, if you find that, use E=0.5mv^2 and solve for v.

EDIT: I've found that m=44-63 g on average for an egg and I think bone seems to be E=10 kNm. (this may be wrong as v=475 m/s or some large number)

EDIT2: YP (bone)=110 MPa, E(bone)=1.50x10^10 Pa.

U= ((YP)^2/2E)*V.

Assume volume V=1 ft^3 overestimate...

I am overdoing it aren't I?


EDIT3:
U=11421.12812866666666666666666666 J and using m =55g
v=455.6938391800646965014633122355 m/s = 1019.3580859913105641519593212432 mph

which...is near to what I found initially, it seems strength of materials works well. This is assuming no air resistance.

And according to my numbers, your egg would break due g-forces before it reached the other person most likely. Then again, you'd essentially be pointing a large rocket launcher at a person.

Not unless you put a nail in it. The egg itself isn't strong enough to do any damage. The way I see it the worst you would have to deal with is some bruising, and that's if you're really unlucky. Like I said you would need something else inside of that egg to make it a deadly weapon.

As long as the projectile is moving fast enough its mass shouldn't be an issue and I'd think it'd be able to cause some nice blunt force trauma to the 'ol noggin. Whether a device to launch an egg at the speed required without destroying it is questionable though.

At high enough speeds, straws of hay have gone through trees before, so I'm guessing it's possible.

No it can't. not enough mass and not a high enough velocity. (thanks mythbusters!)

If I'm not mistaken, wouldn't a hardboiled egg not have enough structural strength?

Also, and bear in mind that I'm not that great at physics, wouldn't it need to have more mass to be able to do enough damage?

I'm not even sure about the density/mass/strength of hardboiled eggs though, to be honest...

For an egg to travel fast enough to kill someone I don't see it making it past the initial blast. It would probably be ripped to pieces rather quickly.
I'm pretty sure the only way to really be able to do what you described is to maybe launch it from over head, and let the force of it being fired, and the force of gravity act together to propel it faster towards the person. The only problem is that the friction from it traveling past the air molecules would most likely rip it apart before it could harm anyone.

I feel like if launched fast enough I could kill you with a marshmallow. Kinda like if you fell high enough into a body of water it would kill you.

But I've failed almost every science class I've ever taken so I'm probably wrong

Here's an idea, what if you got it up to that speed gradualy, without any initial blast? would it still fall apart, or stay together? Sorry for making the question more confusing, but just saying you don't need to blast it to get it to a high speed.

It might be possible, but my initial theory is no. I didn't take physics or anything, but I do know that you can safely break an egg shell on your forehead, and the actual egg has a consistency like jelly. I think it would give you a nice concussion.
Though the more I think about it, the more it seems possible.

The force of friction with the increasing force due to acceleration might cause the shell to break.

F=ma, so with a enough velocity it could be fatal. Wind resistance isn't going to stop it reaching a certain velocity.. an egg being thrown is a different situation to an object being dropped, where the combined simultaneous effects constant acceleration and wind resistance create a terminal velocity. The egg being thrown is initially under a lot of acceleration as it is thrown, then under acceleration in the opposite direction as it penetrates the surrounding atmosphere, and finally under a lot of acceleration when it strikes the target. The question is whether or not the egg could stay intact while travelling in atmosphere at a velocity sufficient to overcome the wind resistance and still hit hard enough to kill. It could well be that travelling through the air at such a velocity is enough to make it burn or shatter.

In a vacuum or a near vacuum it definitely could kill. cf. damage to satellites by tiny pebbles orbiting the earth at enormous velocities. But in such an environment, you're already dead from asphyxiation.

block a major vein, stop the blood from reaching the heart, eventually it will stop the reaching the brain, therefore killng the person (but you have to be pretty fvcking sadistic)

The only way I could think of that working is my dropping it at a great height.
The only thing is that it would be a waste of time, and money to get it up high enough for you to hit someone, and still cause harm. Even then though it would most likely be ripped apart because of the speed it's traveling, and the friction in the air. Might as well just buy an actual weapon to take someone out with.

If you drop a penny from a skyscraper, it leaves a crater...
Based on that logic, a hard-boiled egg could have similar results with enough speed...

Maybe a baseball pitcher could kill someone by throwing it REALLY hard.

water has half the strength of concrete due to surface tension. its very easy to get killed by water. the problem with the marshmellow is getting it that fast due to wind resistance, how ever if you compressed said marshmellow into a pellet that would be way more feasable
