It's also the prime reason boat propellers get worn down, cavitation bubbles constantly hit the surface until they form dents in the metal all the way until there are giant holes in the blades
how does one reduce this?
@@datona13my assumptions are more numbers of smaller blades
@@EvilNeonETCwouldn’t that make each individual blade smaller and therefore easier to deform. Like the ratio of size to force experienced would be the same… I think
I saw a video of Elon Musk explaining cavitation in relation to a rocket engine and it got me really interested in the subject it’s fascinating that these concepts play a role in what most people consider far advanced science when in reality rocket science is grounded in very basic concepts
Either lower speed or get better turbine material
"Hey, I know this one cool party trick!"
*smashes bottle with a hammer*
😐
So this is what Maureen ponderosa is up to
Typically it’s not done with a hammer, but with the palm of one’s hand. Hence why it’s called a party trick
Because science
It's a rubber mallet. A hammer would just smash the bottle 🎉
@@alyschneider3417 Yeah, and it is funny that she demonstrates this "party trick" with a hammer, while calling it a "party trick". People who wouldn't know better, would arrive at a party with a hammer. xD ^^
It always shocks me just how fast glass breaks, even in the super slow motion videos it still often looks instantaneous
Slow mo guys did a video on it
That is because it basically breaks instantly. Glas is a very hard but also very brittle material. Unlike steel there accures no kind of deformation processes before breaking. Or at least only a little.
@@codyfeiler911I was thinking that myself. Didn’t they have to go to like 100,000 FPS before you could see the cracking of the glass travel? Or was it higher?
@@virtual_bomber5698 i think higher because the speed glass breaks like 1500 ms and i think it was 400k frames or even higher
@@kazboven9744 1500 ms = 1.5 seconds
Hey look at my party trick *wastes a beer*
Don‘t do that with a german around, he will make you to mürbeteig😅
Just drink a beer and fill the bottle with water. Also it is still a strength test of sorts, so practice when the people you want to impress aren’t around.
fun fact: this does not work with carbonated liquids! including beer
There's more to life than alcohol
It doesn’t work with beer, it must have water in the bottle

Reminds me of the mantis shrimp strike. They create more damage because of the created vaporized water pocket, Not just the force of the strike itself.
I was about to type out the same comment but saw your first!😂
Did you know that depth changes aren't made to hit subs directly but instead to create immense pressure by exploding displacing water than the water implodes back into place creating pressure waves that rupture the hull of the sub
@@zakgrubb7512 subs are made after all to withstand positive pressures acting towards it. Hence why they're heavily pressurized from the inside to not buckle, however when you cause a cavitation in the water, you create a negative pressure acting on the sub and the internal pressure vs the extremely low pressure outside of it, causes the rupturing of the hull.
Science is neat.
But that strike is still terrifying lol
The punch also heats the water up To its very amazing
When we do this party trick we're just doing our best mantis shrimp impersonation

It's simultaneous nucleation AND cavitation! Very cool!
bro was about to explain this, and then she said "awt awt, lemme take it from here"
Similarly, mantis shrimp strikes also create cavitation bubbles that collapse and deal more than twice the damage of the initial strike.

@@blueburger4wtf is "long covid"???
@BoutThatAction 🤦♂️where have you been since 2020? 😂 long covid is basically just as mysterious in terms of symptomatology as covid, but it specifically refers to long-term negative effects from the physical toll of an initial covid infection. So basically, if you got cardiac (heart) or pulmonary (lung) scarring from covid, neurological symptoms/changes from covid, or any other physical damage that covid caused to your system, you could then possibly experience a whole host of complications on an ongoing (sometimes permanent) basis and the symptomatology (like covid) is kinda all over the place, unique to each individual, and does not respond to treatment in the same way that symptoms typically would pre covid. Some people have arrhythmias, permanent brain fog, weakness, lethargy, trouble breathing, coordination issues, cognition issues, and various other conditions as a direct result of lasting damage from an initial covid infection.
that was cool how it flashed throughout the bottle before breaking the glass
I remember that the old Snapple bottles did this a lot. People got into the habit of slapping the lid prior to opening to basically shake up the contents, and then the bottoms would shatter and pop off.

For a second I thought you said civilization LUL
I knew it was cavitation, but never thought about why. Now I'm told, inertia seems so obvious
@philrod1 not exactly, she not only neglected but disregarded the immediate pressure stored in the neck of the bottle. Without that high pressure stored there the collapsing cavitation bubbles would not create downward force of inertia to pop the seal on the bottle. It would simple escape the bottle neck.
@@TheDeepDiveLLC that doesn't seem very well thought through
@@TheDeepDiveLLC The only thing that would create pressure in the neck would be how much air you force into the neck, which would be negligable. You are pretty much just capping the bottle really fast. You could add way more pressure blowing into the bottle which would do absolutely nothing.

@@Curly_Fry.d haha, true! It’s all related for sure, but this to me is more like cavitation in a pump or propeller, vs piping system water hammer. Regardless, it’s all cool stuff.
Could it have something to do with the bottle neck, and increased velocity?!@@Curly_Fry.d
Actually, nope. Cavitation and water hammer are very different phenomenon. Cavitation happens bc bubbles go from high pressure to low pressure zone and literally explode; watter hammer is bc the inertia of water moving inside a pipe and suddenly closing the valves, making water hit the components of the system.
In the case it might seem the inertia of water provokes cavitation, but water is static, it is the bottle what is moving, water didn't press on the bottle.

Brilliantly clear explanation- well done!
Mythbusters showed this when they were still running. Crazy stuff.
So did Mark rober and the backyard scientist
The phenomenon is called Hydraulic Shock or more commonly referred to as Water Hammer and the mathematical equation for it is Δp=cdΔv; where Δp is the change in pressure [lb/ft2 (kg/m2)]; c is the velocity of pressure wave traveling back toward the water sources [ft/sec (m/sec)]; d is the mass density of water [1.9 slugs/ft3 (979.2 kg/m3)]; and Δv is the change in water velocity [ft/sec (m/sec)].
Also "hydrodynamic ram" if you're looking at bullets hitting fuel tanks. :-)
Yes, you are correct. The phenomenon you're referring to is indeed known as water hammer, or hydraulic shock. Water hammer occurs in a fluid (like water) when there is a sudden change in the flow rate, leading to a rapid change in pressure.
The equation you provided, Δp = cdΔv, is a simplified form of the water hammer equation and is commonly used to estimate the change in pressure caused by water hammer. Here's a breakdown of the variables in the equation:
Δp: Change in pressure (resulting from water hammer)
c: Velocity of the pressure wave traveling back toward the water source
d: Mass density of water
Δv: Change in water velocity
This equation helps in understanding and predicting the effects of water hammer in a fluid system. Water hammer can occur in pipelines, plumbing systems, and other fluid transport systems when there are sudden changes in flow, such as the closing of a valve or the abrupt stopping of flowing water. Managing water hammer is important to prevent damage to pipes and equipment in these systems.

Cavitation is the same reason centrifugal pump, impellers are destroyed by restricted suction, causing the same affect.
Also how ultrasonic cleaners work. To test if they are working, often a sheet of aluminum foil is dropped in and if working, thousands of micro holes are formed through it.

Btw, that’s how torpedoes works against battleships, they create an area in which there is not water in anymore just for the water to collapse rapidly on the enemy ship’s hull to create a crack in it.

Cavitation bubbles are a very interesting phenomenon.

Reminds me of one from xkcd
"The lesson: If the optimist says the glass is half full, and the pessimist says the glass is half empty, the physicist ducks."
Damn thats good
And the engineer says that the glass is twice as big as it needs to be.
@@jonmarcus1954The glass was designed with a safety factor of 2 🤓
Please explain your joke
I recommend looking up the article.
But in short a glass half empty can be interpreted as a big cavitation bubble.
Water cavities collapsing and concentrating energy is also the mechanism that allows torpedoes to snap ships in half.
:o that makes sense, never thought of it though, thanks!
Cavitation is bubbling resulting from the static pressure of a liquid dropping below the vapor pressure. A torpedo uses high explosives to send a shock wave out that damages the ship. Following the shock wave by anywhere from a few dozen to a few hundred milliseconds is the bubble pulse that comes from the expansion of high-temperature, high-pressure gas. As the gas cools, the resulting void collapses, often without much compression as some of the void is open to the air due to the relatively shallow depths at which torpedoes usually explode.
It's not the same as cavitation, where bubbles form due to low pressure and then the temperature increases as the volume declines due to surrounding liquid pressure, compressing the gas and thereby heating it.
It is also why ships' propellor blades erode fast around the edges.
@@JarrodFrates
I'd like to assume that You know that torpedoes work better when they hit the keel of the ship rather than waterline, that's because the massive void/bubble that is formed by the explosion then collapses and (since water rushes back in from every direction except from the ship) all that kinetic energy is concentrated and the water is formed into a jet that can snap a decently large ship in half. Shockwave alone will never do that at the yields involved, as most of the energy never "hits" the target.
@@nfboogaardWe design propellers to minimize cavitation. If you see a propeller made in the past forty years that has noticeable cavitation damage then it means that it was run faster than recommended.

That's a terrible party trick - "Watch me get broken glass and beer all over your floor!"
Try doing it a bar instead. Just kidding!
If this trick relies on the collapse of cavitation bubbles, then beer may not work, due to the gas held in suspension. Also don't waste beer, unless it's Bud Light. 😂
@@gorillaauwhats wrong with budlight?

Ta daaa!!!

That was very very upsetting for the anti cancel culture, "you can't offend me😌" crowd so they got very offended and cancelled Bud light 😂 buncha babies.
