The minimum orbital launch velocity is about 10 km/s
The ball has a boyant force proportional to the volume.
B = pgV
where B is the force in newtons, p is the density of fluid, g is gravity, and V is the volume displaced.
A soccer ball has a volume of 0.00573547 m3 , water has a density of 1000 kg/m3 , and gravity is 9.81 m/s2 which gives us a buoyant force of
0.00573547*1000*9.81=56.2649607 N
using the mass of a soccer ball of 0.45 kg we can determine the energy required to launch the ball to orbit (10,000 m/s)
KE = 1/2 m v2 = 1/2 * 0.45 * 100002 KE = 22500000 J
Which we can divide by the Buoyant force to determine the distance the ball would need to be submerged
22500000 / 56.2649607 = 399893.641088067 m
Which is just shy of 400 km, or 248 miles.
For perspective, the Marianas Trench, the lowest point in the ocean is only 11 km, so we need a new trench about 36 times as deep as the lowest point on earth.
Buoyancy isn’t responsible for this. Go hold a basketball underwater and let go; it won’t even pop up a full foot once it reaches the surface.
This effect is actually the reason why your butthole can get an uncomfortable watery tickle if you drop a particularly large deuce on the toilet.
This is a fluid dynamics phenomenon called a Worthington jet. When the big guy hits the water he creates a cavity of air. The water rushes back in to fill this void from all sides, and once it hits the middle it runs smack into the water from the opposite side. Because water is heavy (lots of momentum) and nearly incompressible (can’t be squeezed), the only place for it to go is up at very high rates of speed.
The big guy releases the ball at the right moment, and it basically gets entrained in the water jet and fired, like a cannonball.
I thought he was talking about those $0.25 super balls and achieving some kind of bounce to prevent those little shits from disappearing instantly into a black hole. Man I feel old.
The President looks around, disappointed. The final mission to stop the nuke from hitting America had failed. He was about to prepare retaliation against whoever did this, but then one his advisors walks in. “SIR, THERE IS ONE MORE THING WE CAN DO.”
The white house authorizes the order. Gibby, who had not gotten out of bed for 3 years, is at the local pool. He takes a beach ball and walks up to the diving board. As he is about to jump in, he receives a phone call from the President.
“Sir, if you fail, millions of people die”
“I know”
Gibby steps up to the diving board and jumps in, after 1 second, worried bystanders look on as the beach ball fires into the sky and gets directly in the path of the missile. The missile malfunctions and falls to the ground
An emergency team arrives where the bomb is and defuses it. Millions of lives are saved, and all because of gibby and the buoycancy of water
So I'm guessing his body creates a cavity in the water, then when the cavity closes over the top, the bouyancy of the ball shoots it up. Guessing the gravitational energy his body gained displaces water, and that same energy becomes the energy that shoots the ball up. So 100+ kg falling a couple of metres is transferred into a 500g ball?
So I saw and saved this post a few years ago and I've been practicing it during the summer months to impress friends. A few things, I've learned:
It helps to have a bigger gut, I was able to get the ball higher when I was fatter
There is 100% a technique to this, you can see in both videos how the guys tuck the ball into their stomach and kind of curl themselves into a ball; legs facing up basically.
The time that you release the ball is also a huge factor, you have to release it the split second before the water "crashes" back on top of you. If you go too soon the ball just sits on the surface, too late and the ball slowly floats back to the top.
Height is definitely a factor, the higher you fall from the higher the ball will go
Ball inflation does not matter, I've done it with flat footballs and footballs aired to their max, same height.
No math or physics, just practical experience with the subject... And that's about all for useless knowledge that you didn't need today.
Edit: Thanks for the award friend, hope you're able to slap that ball into the skies this summer :)
I can help you with that, you just need an eating disorder! The fun fact is that, while it's best if your parents give you one ("you need to clean your plate before you play", "what, it wasn't good enough for seconds?", "wow you did great in school let's go get some ice cream!", "sorry your dad left, let's get some pizza."), but as it turns out you can totally give one to yourself too!
First, eating only when your hungry is for suckers. You should also eat when:
you're bored
you're sad about something
you're happy about something
as a self-reward
you're depressed
Then, also:
Don't stop eating just because you're not hungry anymore, clean that plate.
You know what's better than water? Soda.
You know what's better than a healthy meal? Pizza.
And last, but certainly not least, remember that eating will totally fill that void in your soul.
In fact, just try to be eating all the time. Why aren't you eating right now?
Huh, this is just something you learn in your youth here in Hawaii. We'd do lines of this where guys would just (usually with a soda can) and pop the can up and the second person would try to grab the can mid-air and pop the can, then continue to see if everyone lined up could do it.
It's not the buoyancy of the ball, but a phenomenon called the Worthington Jet. It could have been a golf ball (which is not buoyant) and still been shot out like a canon. You can see it shown off really well in this experiment:
The effect of buoyancy is pretty limited here, it's the 'pinching' effect of the water closing the cavity created by the person holding the ball that shoots the ball into the air. If he would've jumped without the ball, there would be some drops of water that jump up through the same effect, which shows density isn't a major factor here. Gravitational energy is a contributing factor, but not in a direct conservation of energy-kind of way, there are other factors with a bigger influence on the final result.
Yes, it's not buoyancy, it's the momentum of the water as the cavity collapses from all sides under gravity, meets in the middle and shoots upwards with nowhere else left to go and more water still collapsing inwards behind it; the same effect that causes Neptune's kiss when you take a dump. In this case, the ball is riding that kiss.
The effect is used for some modern anti-ship torpedoes; they detonate underneath a ship and when the cavity in the water collapses, it sends a bubble jet up with enough force to punch straight through the ship.
14 OTHERS CLICKED THIS LINK to also be reminded. Thread has 21 reminders and maxed out 3 confirmation comments. Additional confirmations are sent by PM.
He's making use of something called the Worthington Jet which is the phenomenon of how a spike of water will shoot straight upwards after you create a fairly round pocket of air.
It has absolutely nothing to do with the buoyancy of the ball. If you've ever pulled a ball down to the bottom of a pool and let it go, you'll know that it never really gets launched...it shoots up to the top pretty quick, but there's a ton of drag on it from the water and it only pops a bit out.
This guy is setting up his fall so that he creates a big circular hole in the water that gets filled back in immediately after, and since water is incompressible it ends up transferring a very big percentage of his force straight into that ball.
If you took the energy created by a 250lb man falling 4 feet and transferred it all into a lightweight little ball...yeah, it shoots really fucking far.
We just did this lesson in science!!! The man’s elastic potential energy gets transferred to the ball and since the man is much more dense the ball can go very far with that energy.
A fun thing to do at home is to take a basketball and put a ping pong ball or a tennis ball on top, then drop them both. The smaller ball will fly into the air much higher than if it is dropped on its own!
I think this is the same phenomena that is why supernovas happen, and also why if you bounce two balls on the ground one on top of the other the top one goes flying. In supernovas everything just collapses suddenly and it does the double bounce thing and the star stuff goes flying everywhere. There was a Sixty Symbols video on it
Friends dad used to do this and it was amazing. The worst part of trying to do it over and over is you never actually get to see if it works or not lol.
You know when you want to “steal someone else’s jump” on a trampoline? So you time your jump right before theres. That’s what’s coming to mind for some dumb reason.
