Hydraulic Press Action Can you change your channel name? You hardly ever do Hydraulic Press videos anymore, and it makes you sound level meter you're just imitating HPC.
I gotta be honest but the 1000 FPS camera isn't enough. it's still too fast for me to see how the ping pong ball made the contact with the Apple and blown to pieces.
Yes, it looks kind of like the ball is already broken before it hits the apple and it would explain why all the damage on the apple is in a ring. The video only has about 1 blurry frame of the ball before impact. Do ping pong balls pop under vacuum?
Instead using ping-pong, can you use something more aerodynamic and shoot it vertically so we can see how high it will go. And for shooting from this gun you need a faster camera, or Slow mo guys. Good luck.
+my520graj and shot it vertically- (shot) Shoot high will it goes- (goes) Go, fly you need fastest camera- (fastest) A faster or Slow mo guys. Good luck.- (dumb) Not everyone has access to a "Slow mo guys" They're quite expensive to buy at Walmart and no one has that amount of money.
I think it'd be interesting to see what would happen if you built up a whole lot of air pressure on one end of the vacuum tube and find a way to rupture the seal with the massive air pressure behind the ping pong ball to shoot it harder.
0:50 actually, it's been done without vacuum. The speed of sound limits the speed of a sonic wave but compressed air can expand to atmospheric at mire than mach 1 speed because it's not acting as a wave, but as a spring. There are a couple of videos if someone is curious...
Attach a pressure chamber right behind the Mylar rupture sealand when you get the cavuum down to pressure, pump up the pressure chamber until the Mylar breaks, and compare the velocity to the rupture without the pressure chamber.
I think the ping pong ball is bursting when under vacuum, prior to being fired. If you put a small hole in it this may not happen. It may implode after exiting the barrel, though. So maybe several small holes may be necessary to prevent implosion. Alternatively, fill the ball with expanding insulating foam used to fill cracks around doors and windows. That should keep the ball from bursting or imploding.
Ive been watching some of your vacuum chamber vids... btw did you know that if you place a vacuum cleaner hose in front of a roach it will run straight in because of the 2 pressure sensing "spikes" on its rear end, the vacuum simulates an attack coming from the other end of the roach. I bet there are some cool experiments you can do with this. Love the vids!
Wrap copper wire around. PVC And use a magnet as peojectile. 2 experiments here. 1) see how much juice can be generated. 2) add power to the coil and combine the vacuum & electromagnetic! ( look out)
+davie didgood How can this be classified as art? I mean I am glad you are supporting this dude, but it becomes a lot less credible when you say something that this video cannot even class under.
Art is very subjective. Some arenas such as performance art can be very contrived and pretentious and the 'high art' critique that supports it isn't art in my view but others salivate over it. I see images from the hubble of gaseous nebula and see them as art. Some of the still frames from this video, in my eyes, is art.
don't know if you'll read this but why not make a 2 chamber cannon with a vacuum on one side and greater than 1bar on the other, what kind of power would this produce
I'd like to see you make it even more powerful, if possible. I feel like if you had a much stronger rupture seal on there, and then in addition to the vacuum, instead of just atmospheric pressure rushing in, put a tank of compressed air that will rush in (hence the much stronger rupture seal). Or...something like that.
i am not critisizing, but what i noticed that the area where ping pong ball hit the apple, i looked mushed and pre squished to make it penetrate more. Normally i dont think ping pong ball would leave that much of damage on apple. but it was nice experiment. sorry for my english spellings.
what if you had the vacuum pipe connected to another pipe that has pressurized air in it and after you pop that pressure cap thing see how fast the ping pong ball goes (not sure if the pressure cap will hold up in this scenario)
so it's sort of half a hyperloop. I wonder if you could somehow magnetically accelerate something inside the plastic pipe by wrapping copper coils around the outside of the pipe? You could then have a solid end cap on the breech end and the mylar disk on the muzzle. A metal bolt could be accelerated to hypersonic speeds if the current and length of the tube was big enough and then come smashing out into the air...
Is it possible to use a heavier object? Or something with a 'point' of any sort? My thought would be to machine a dart of some sort, maybe hollow in the head that would fit the pipe near perfectly. That would allow for more penetration and potentially a larger amount of inertial force.
I didn't understand the explanation of the mechanism so excuse me if I'm wrong, but instead of using ping pong ball, boils you use a led ball? it would make some epic shots, or just fill the ping pong balls with sand to make me harder
Try to make the PEX trick? Press PEX tubing to a thin foil and when you reheat it it will restore itself to a tube. You would be the first on internet to show that....
Wait wait wait, 3 times the speed of sound in a vacuum? Ehm, not quite... The hyperloop only promises around 1200km/h, because the speed of sound is 1270 km/h at ambient temp. Thunderf00t has some great videos called "hyperloop busted", where he talks about leaks rushing in *at* the speed of sound. He has some very nice demos and explanations on this topic. Anyway, *the part that is correct:* you will get insane speeds, simply because you can reach the speed of sound at all. Here is how you can look at it: it you have one tube with 1 atmospheric pressure, and another pressure vessel with 2 atmospheres, then the air will rush in, but as soon as the air get's in the tube, the pressure in the tube rises, slowing down the air. See? In order to get close to close to the speed of sound you need to have the pressure vessel having a pressure that is waayyy higher than the tube; either by generating a big pressure with blackpowder exploding, or by just sucking out of the tube. --- The speed of sound *actually is* the speed at wich the particles of air move, so if air particles are moving 3 times the speed of sound, they are moving 3 times faster than they are actually moving. See the problem? Anyway, getting to the speed of sound is not bad, that is still quite fast man. Oh and don't forget, 1270 km/h is the same as 343 m/s or about 800 mph; don't confuse the numbers.
But since there's no pressure at the exit end of the tube, there's no air pressure to slow the ball down being accelerated. The speed of sound varies depending on air pressure, and since the air in the tube is at a lower pressure, the ball is only accelerated by the initial rush of air, and as that inrush of air slows down as the pressure equalizes, the ball's inertia keeps it going faster than the pressure front of the inrushing air, and since there was no air holding the ball back, the flexibility of the ball would push back against that pressure front and spring it forward at a speed greater than even that initial pressure front, which could allow it to exceed the speed of sound all on its own. However, since the pressure in the tube is lower than atmospheric pressure, air is free to move at the higher speed of sound in a near vacuum, so the ball still could reach a speed greater than the speed of sound at the altitude/pressure where the ball is fired. But since the speed of sound carried by air *_depends_* on air pressure, the actual speed of sound inside the tube is a higher ground speed, so while technically the ball may not be exceeding the speed of actual sound, that doesn't mean it isn't exceeding the speed of sound at atmospheric pressure at standard temperature and pressure within the tube or shortly after leaving the end of the tube. With its large surface area and low mass, it certainly wouldn't be able to maintain that speed for very long, though.
The speed of sound has little to do with air pressure and a lot to do with air _temperature_ This is why at even very high altitudes, the speed of sound drops off a lot less than the pressure would indicate. Without getting too technical about it, the maximum speed of the ball will be essentially the average speed of air molecules: no matter _how_ great the delta-P, the ball cannot outrace the air molecules that are pushing against it. tl;dr: sasja is right, and the channel claim is wrong. The ball will not go at 3 times the speed of sound, or even close to it.
How did you make it? :) I'd love to have a video showing how we make this kind of cannon :D Great idea and great video! Ideas of things you can shoot at... a coco could be interesting ^^' and don't shoot at windows :p
This is a good example of how mass has an important effect on a collision, as opposed to low mass and high speed. That low mass ping pong ball gets its butt kicked when it hits a measly apple.
Hi an open question: do we know for sure that the ball is supersonic? The fact that the air pushing it is Super sonic at the entrance do not warranty that the ball will be. Did you calculated the speed on other video , or am I missing something?
ive gotten it to about mach 2 buy adding a compressed canister at the end of it and an area to dampen the air cushion at the end which slows it down quite a bit
Can you put a lighted candle in a vacuum chamber? See what happens to the fire Im curious cuz fire is made of oxygen but I dunno what will happen if it's in a vacuum chamber
maybe you could try doing the same experiment but this time coating the ping pong ball with something that would make it harder and this time shooting it at larger objects.
nice video but Mach 5 speed would blow up the pipe. 1000 fps isn't enough to see the ball. 3-8 times the speed of sound would blow up the apple, the ball would disappear.... try using a 1.5748 bearing ball as a projectile.
Testicals vs Supersonic ping pong ball

DESTROYER 200 he did but they didnt explode so he crushed them with a press
what happens if you use a golf ball instead of a ping pong ball please make video on it
I gotta be honest but the 1000 FPS camera isn't enough. it's still too fast for me to see how the ping pong ball made the contact with the Apple and blown to pieces.
Sack Boy true
Camellotion Theodorsen they need more than 1000 FPS camera. coz this is really an interesting experiment. thumbs up for that.
I was just thinking he should team up with the Slow Mo Guys to run this and maybe other experiments using this thing.
Yes, it looks kind of like the ball is already broken before it hits the apple and it would explain why all the damage on the apple is in a ring. The video only has about 1 blurry frame of the ball before impact.
Do ping pong balls pop under vacuum?
Right, we need 5,000-10,000 fps footage.
Who fancies a game of extreme ping pong?

This channel keeps getting better and better
That is incredible how much energy the pingpong ball had!
so does flash have supersonic balls? lol
Der mähdrescher30 g no flash doesn't even exist
But Sonic does.
-Link from Legend of Zelda.
Link You're really nasty...
Sonic does
this was one of the best and diffrent from all videos i ever say on youtube ,,,,,njoyed,,,, thnx
please keep doing this! it's awesome :)
oh wow now that is amazing! How fun and don't let the kids shoot each other with that, wow crazy! loved it!
0:50 actually, it's been done without vacuum. The speed of sound limits the speed of a sonic wave but compressed air can expand to atmospheric at mire than mach 1 speed because it's not acting as a wave, but as a spring. There are a couple of videos if someone is curious...

Shoot water! Shoot oobleck! Shoot a car window! I want to see more of this please!
Shoot a phone book or see if other projectiles work like paintballs, nice work btw
That is awesome. What stops the the Mylar from breaking by itself under all of that pulling pressure?
Bro I love your channel please keep up the good work
That's awesome. You're very creative!
OK now that was awesome, break a sheet of glass with the ping pong ball
That all was pretty awesome!
really cool its like an opposite air cannon
that is amazing man, love the video
Wow! That is very powerful!

You should do more with this sonic cannon! Try something hard like a cinder block or maybe put some obleck in a ziplock baggy and shoot at that
Would love to see the infamous toothpick through a 2x4. Loved seeing glass denting steel.
GOD I LOVE YOUR VIDEOS AHHHHHHHHHHHHH!
This is really awsome! Maybe you could draw or make an animarion of how it works. And I am really intrested in how it injured "human" flesh.
Damn, u never run out of ideas :-)
Wrap copper wire around. PVC And use a magnet as peojectile. 2 experiments here.
1) see how much juice can be generated.

Woah! That was cool
Can you crush popcorn with the hydraulic press and see if you can write on it like paper?
+TheTrollingHACKER interesting idea. I might just try that!
+Hydraulic Press Action I got the idea when I crushed a piece of popcorn and it turned white and flat, like a piece of paper!
TheTrollingHACKER try writing on it than lol
How far will it shoot?
Supersonic balls... Balls, BALLS 😂
Absolutely awesome. You should also try to use other things as ammunition
very cool science/art - i know they're expensive but I'd love to see your vids with a higher frame rate slow motion cam.
Still great work.

That apple had a family you monster 😱😱😱🤣🤣🤣
That is impressive!

"What?!?"
"Supersonic Ping Pong Ball."
"Huh? AAAAUUUGH!!!"
Doesn't quite work as well, does it?
Could you try firing ooblek out of this?
Orbeeze?
I roasted one of my friends so hard that the fire alarm went of
Legend has it that the half of the ping pong ball is still going 2:24
don't know if you'll read this but why not make a 2 chamber cannon with a vacuum on one side and greater than 1bar on the other, what kind of power would this produce
Imagine going enjoying your day,then all of a sudden you get smacked by a ping pong ball
That's crazy and awesome.
yea but does it hurt?
soo cool I never knew a ping pong ball could do so much damage. next maybe supersonic ping pong ball vs iPhone?
I'd like to see you make it even more powerful, if possible.

please make more of these
Do Cold welding in a Vacuum chamber! PLZ!
I think it will do the same damage without any ping pong balls or anything just with the presure that is coming out of that tube
what if you had the vacuum pipe connected to another pipe that has pressurized air in it and after you pop that pressure cap thing see how fast the ping pong ball goes (not sure if the pressure cap will hold up in this scenario)
This is going to be Viral

With a properly designed inlet, Mach 3 would be easy. Many supersonic wind tunnels rely on this very principle. Google "Suction Tunnels"

YAWN, call me when you have a hypersonic ping pong launcher.
This is a good example of how mass has an important effect on a collision, as opposed to low mass and high speed. That low mass ping pong ball gets its butt kicked when it hits a measly apple.
You harmed the apple, you monster! :P
At 2:20, my mouth flew open!! That was beautiful!!❤💛💚💙💜💗
Hi an open question: do we know for sure that the ball is supersonic? The fact that the air pushing it is Super sonic at the entrance do not warranty that the ball will be. Did you calculated the speed on other video , or am I missing something?
Try contacting the slomo guys to film your next canon test, I'm sure they'd love to feature this on their channel
What's that point ?
if a ping pong can do this, then what can a supersonic melon launcher do?
XD
I just love how the ping pong balls just go into two pieces at least after hitting the apple
ive gotten it to about mach 2 buy adding a compressed canister at the end of it and an area to dampen the air cushion at the end which slows it down quite a bit
So could it shoot through your hand?
There's your problem. Your apple broke your ping pong ball! 😂👵
Do more of these videos please
Can you put a lighted candle in a vacuum chamber? See what happens to the fire
Im curious cuz fire is made of oxygen but I dunno what will happen if it's in a vacuum chamber
Super sonic golf ball!
I'd like to see if it could cause severe damage to something like a dead pig or ballistics gel.
does this mean you can make anything (that will fit in the launcher) break the sound barrier?
You sounded out of energy in this video. Is it just me thinking that? Are you alright?
Great vid btw, as always :D
You should let the slo mo guys have a little fun with your super sonic ping pong launcher
swap pingpong ball with golf ball
and congratulation, you've made a brand new weapon
I want to see how far it can fly!
I would like to see you shoot it against a ping pong paddle. Would it leave a hole in the center, or would the paddle completely break it half?
What about keeping it as it is, but let the air come from a pressurized tank? Wouldn't it make it stronger?
you should've potted the the tube thing alot further it would look cool,
and who know it may make a sonic-cloud...
can you put a capsule with a gopro inside of it into the cannon and shoot upwards? that would be extremely cool!
how quickly does it decelerate, and what is its maximum range for throwing a ping pong ball?
maybe you could try doing the same experiment but this time coating the ping pong ball with something that would make it harder and this time shooting it at larger objects.
nice video
but Mach 5 speed would blow up the pipe. 1000 fps isn't enough to see the ball. 3-8 times the speed of sound would blow up the apple, the ball would disappear....
try using a 1.5748 bearing ball as a projectile.
Even at 1000 fps it looks fast.... super cool
any chance you can get your hands on some ballistic gel to shoot at?
today I am going to test my super sonic balls.
*grabs girlfriend *
Dang that's a big hole.
OK you really must have lost your mind a long time ago to even be thinking of a super sonic ping pong ball launcher!!!
Shoot ballistics gel. Also try shooting a cue ball.
If you shoot a bullet through that pvc pipe vacume will the bullet speed up due to less air - resistances?
