Vacuum experiments with our new vacuum pump

Testing out our new vacuum pump. If you want to see something inside of that chamber please leave your suggestion in comments

[@Viking0612]

I have to admit, out of all the vacuum chamber experiments on KZbin, this one instantly became the best. I have never seen anyone before demonstrate the inability of sound waves to propagate through a vacuum.

[@kenwolfe6093]

After doing the water and moisture experiments, you need to change the vacuum pump oil, or at least close the valve and let the pump run down to 28 or 29"Hg for a half hour or more to drive the moisture out of the oil in the pump. Doing this will keep the pump working like new for a long time. Leaving the moisture in the oil can and will cause corrosion and other problems. Very cool stuff you guys are doing! Thanks for making great entertainment!

[@Beyondthepress]

I run the pump for a while yesterday until the oil was looking normal. I put the pump on again today to be sure. Perhaps I should buy more oil to be able change it after watery stuff. If this vacuum stuff really gets of I am probably going to get more powerfull pump and leave this one for dangerous stuff like exploding sport balls.

[@kenwolfe6093]

+Beyond the press you can never go wrong changing the oil in a vacuum pump. The oil is used for lubrication AND as part of the pumping process. So, if the oil is contaminated it won't pump down very well and the pump will get damaged also.

[@68Squid]

It was really cool listening to the alarm clock slowly get louder as air was added. Never seen a practical demo like this

[@nateshattuck1512]

Hearing you say new and interesting swears is what brings me to your channel(s). You delivered!

[@Gardab]

I must say I totally loved your video. A thumbs up is not enough to show it. In school they always teach about this things, but you never get to see it. This is an excellent (and funny) demonstration about that. Cheers to Mr. and Mrs. HPC

[@kithpendragon]

Thank you for replicating science experiments! This is one of the most important things that many scientists fail to do.

[@0zeroburn]

So this video is kind of the polar opposite of the hydraulic press.

[@epsdudez]

Pneumatic pull?

[@eseagente]

+Epsdude Z nice one

+Epsdude Z WELKUM TO THE PNEEUMATIC PULL CHENEELL

[@thelamb288]

Here is an idea for your vacuum chamber; 1. Get football and de-flate it. 2. Then pump up the football with water!!! 3. Put it into vacuum chamber and remove the atmospere!!! Have fun. All the best, Pete Lambert UK.

[@AdmiralTom]

Put the stuff that you press into the vacuum chamber to see if they return to their original shape

[@petti78]

Nice try :-)

[@sept836]

I was thinking that

[@Widestone001]

That's called Sarcasm if I am not mistaken. :-)

[@mikebarnacle1469]

The irony is that you are in fact the tard for being the only one who doesn't get the joke.

[@General_Confusion]

That pink marshmallow looked very dangerous and could have attacked at any time, i'm glad you saw fit to deal with it.

[@melissametivier4]

sac43 has just won the internet. We can all go home now. Good game, everyone!

[@sethfaulkner1253]

+Melissa Metivier are you an Imgurian by any chance?

[@melissametivier4]

seth stheslayer Nope.

[@rippsteakface]

I think this is one of the best non-press videos. Extremely interesting to see what the vacuum does to everyday objects. I'd like to see you guys try a water balloon, a rubber band ball, a clay animal, maybe some bread, etc.

[@ivyssauro123]

I thought the marshmellow would get thinner and smaller! haha wow! Really nice.

[@jaredmeit6127]

Put a carbonated drink inside. like a soda or beer.

[@TerminvsEst]

Yes Mr. HPC! Please do this!

[@CafeEnergy]

+TerminvsEst yeah, but shake it first and see if the can can withstand the pressure difference.

[@Widestone001]

Where's the fun in that? xD Explosions! And a thick blast shield, just in case. :-)

[@shhmule]

More Vacuum videos please! It's really interesting to see what happens.

[@jugalator]

A fun idea to complement the press. Like a reverse idea. I liked some experiments for teaching too!

[@bdouble69]

[@christiangob9493]

At first you have driven off disolved gases from your water. This explains why it started "boiling" very short after switching off the pump. You could repeat your experiment with boiled/degassed water. Your pump will be thankful if you leave it running for longer periods. Short on/off cycles are usually bad when the pump is cold. Try freezedrying, for instance icecream or strawberries.

[@JohnRysdyk]

You just scared the heck outa me. I got vacuum brakes on my model train.

[@James-mm8gc]

You guys are very creative. Appreciate all your videos.

[@fireworks368]

Would your camera still working in the chamber?

[@Beyondthepress]

I try that next time with cheapest of my cameras. I am bit afraid that air escaping from inside of the camera could broke some seals if there is any on regular cameras.

[@fireworks368]

Make sure you do not put the waterproof case on a gopro if you use one. I think it may crack. Would a spinning fan speed up if there is no air? That would be cool

[@kalma5003]

Sure it will.

[@keyboardfromelbaf6138]

+Beyond the press I've always wanted to see what a can of soda in a vacuum would look like

[@kickpublishing]

I love this guy's accent - its the star of the show

[@theHiddenStone]

Some suggestions : expanded polystyrene / packing foam, bubble wrap, a balloon animal, sponge.

[@MisterScotti]

Your videos are actually very good physics videos. Physics teachers should show them in their classes.

[@jakewestbrook3214]

despite the noise, that looks so much better than the 30 some year old equipment my school's science program had. also, this may be an overdone request, but there should be clay animals put in the pump as well.

[@MightyJustas]

that was actually really good idea. Mayb put some feathers inside and shake it a little bit to see if it moves quicker! Good job press guy, you have been seen by many lithuanians already as some of your videos got posted by media on the internetz

[@doctorbangs]

Hi, Just be aware that the water you evaporate ends up in the oil of your pump! It could get rather corrosive and will attack at any time! :) (Love your work!!!) Will

[@poisnonsei]

I see the beginning of a new channel lol

[@gazmobile]

Why does the sticker on the vacuum gauge say cut the top off after installation, but its still on?

[@jackking5567]

In science we removed the air from a metal oil can (5 litres) - an old style engine oil container. Once the air was out we inflated it back up. Vacuum pumps are awesome machines.

[@megamixa]

The way he says vacuum is great.

[@CaptainEverythingHumorandMore]

Pretty cool guy. Would enjoy having a beer with ya. Thanks for the video and Take care

[@NotRealNamesAgain]

The high to low sound when you allow the air pressure to rush back in is interesting, I wonder if you attached a whistle to the valve's inlet...

[@dazmac4773]

I love your videos mate. You should try an air filled balloon, cans of soft drinks, Spiders, Fruits (Watermelon / Tomatos)

[@GranVlog]

No one can hear you scream in the vacoom pump

[@chemxcore]

*vacoom poomp

[@jorge1734]

and because sound can only travel through air...

[@RezzaNL]

Not only air through a medium.

[@jorge1734]

RezzaNL my bad...

[@nicparker3809]

chamber not pump lol

[@express375]

Things to vacuum.An egg,ping pong balls,different fruit?

[@CoyoteRob]

Hi, how about a "play-doe" figure like you use on HPC. "It is very dangerous and may attack at anytime so we must suck it!" Have a nice day!

[@keyboardfromelbaf6138]

That sounded sexual.

[@BigRedCatFTW]

That's what she said

[@MarvinBug]

Awesome! Try a partially inflated balloon

[@cheeto4493]

or an "empty" balloon just tied off. There will be enough air inside to fill the whole chamber.

[@DonaldKing23]

Marshmallows are always cool in vacuum chamber.

[@i.p.freely2501]

VIDEO IDEA: Make a FREEZE DRYER , do ice cream and meat. also ensure you have a single stage or double stage vacuum pump, and ensure new oil as often as you can, especially if doing multiple try with moist items. Put a thermometer in the item to show temperature drop etc.

[@jrnascimento1448]

Beyond the press, is knowledge too.

[@Hellsslave666]

To freeze the water you need to get the temperature below 0°C while keeping the pressure above roughly 5 mbar (500 Pa). If the pressure get lower then 5 mbar You need a lot less temperature then 0° because the freezing point is different and low pressures. Also after the Temp drops to 0° you need to take away another 334kJ/kg of energy to make the water actually freze. But since evaporation takes away 2265kJ/kg This could actually be possible. I cant really be bothered to do the calculations (which are in an ideal closed system, which is not practically possible), but in theory it would be possible to freze some water by lowering the pressure. It just depends on the temp of the water at the start.

[@AerikForager]

You must deal with that dangerous Purple Elephant... ;)

[@naominekomimi]

How about a lego figure or structure? They have all sorts of air trapped inside the blocks, it'd be interesting to see if they pop when the air goes out or in (maybe try part of one where the blocks are sealed against eachother with glue so that the air inside of the black stays at the same pressure?). Or how about a sealed plastic bag (like a ziplock) to see if it expands enough to pop (Might need to glue the opening for that though), or maybe a balloon?

[@rkirke1]

Electric arcs! Two metal bolts through the lid with o-rings to seal, a spark gap inside and a neon sign transformer on the outside. The appearance of the arc should change several times as the pressure drops. You can also try filling the chamber with argon or CO2 from a TIG welder to get much bigger and more colourful arcs. I don't think there is any x-ray hazard at these pressures (I think x-rays need around 10^-6 atmospheres), but I would keep the voltage under 10kV just to make sure!

[@Boobashoob]

a water ballon. Fill it so there is no air inside... just water. Then get it to boil.

[@touchnova]

Be careful with that vac chamber, you DO NOT want to see (or feel) what happens if the seal breaks. I notice the metal chamber already has a deformation on the bottom (or so it visually appears to be deformed)...I urge caution.

[@davidrobert2007]

What happens when the seal breaks?

[@MMID303]

+davidrobert2007 It will suck the entire universe into to the chamber and create a space/time void. lol

[@touchnova]

davidrobert2007 It creates an extremely violent implosion that can send contents/shrapnel flying upon equalization. If the container fails and only crumples, it's not bad...but if the container crumples and creates a hole at a fold point (think folded pop can) or the seal fails at this (or any) point, you're having a very bad day.

[@davidrobert2007]

touchnova Thanks for the explanation.

[@BerkinGG]

+davidrobert2007 I believe it would implode.

[@MightyJustas]

And heres the list of ideas. Egg, boiled one as well, maybe a steak? Yeah, vacuum a steak. Would be interesting to see it marinated and put in a chamber to see if it makes marinating somehow quicker as the air rushing back in to the chamber and meat sucking in marinade haha. Maybe bubble wrap? Or a dead fish. Maybe a balloon wich is not inflated. No, thats kinda lame, better a lightbulb! Its lame too. ummm... Vodka? Alcohol should evaporate first and as you let air back in it might condense in a cloud. ok, ill just show myself out

[@CrazyKosai]

This is really interesting, more of these pls

[@the_ALchannel]

after next 2 weeks: "welkam to de vahkuum pamp channel"

[@madinatore]

burning sparklers, liquor, grapes and ping pong balls to give a serious suggestion.

[@Widestone001]

Just an idea: That alarm clock thing might have been even cooler if you had placed a GoPro inside the chamber with it, so that we all can witness what's happening inside the chamber. :-)

[@philipkaiser5663]

The Triple Point of Water is at 0.01°C and 0.0061 bar. So you should be able to reach it, but it might require a different pressure gauge.

[@ChumpusRex]

The pump claims to have an ultimate pressure of 0.00002 bar, so should be able to reach the triple point. However, it is a cheap pump, and it may only approach that pressure at desperately low rates. The pump claims to have a pumping rate of 280 litres per minute, and given the performance in this video, the pump rate falls precipitously as the vacuum builds.

[@JuanPretorius]

but surely the pressure gage doesn't actually affect the pressure?

[@philipkaiser5663]

Juan Pretorius The Pressure gauge doesn't affect the pressure but you have to dial in the pressure very exactly so a gauge with a finer resolution is necessary,

[@JuanPretorius]

Philip Kaiser Can't you just use a stronger pump and leave it on for a while? After all, we're after results, not a read out on the pressure

[@philipkaiser5663]

If you want to have water in solid, liquid and gaseous form at the same time in the same vessel, you have to reach the triple point and there is only one triple point. see: img1.mnimgs.com/img/shared/discuss_editlive/2353749/2012_04_20_02_00_38/image6158467625517348632_5427546445302335556.png

[@AllenSAshley]

I had no idea the marshmallows would do that in a vacuum! But it makes sense that it would happen

[@spiros1994]

maybe you can read the temperature of the water with an electronic thermocouple meter(without lcd because i dont know if it can handle the 0 atm enviroment)

[@iwantpig]

lol, you had an air pocket under the glass. try with some strips of something underneath it to stop it popping up. Maybe try shaving cream or i wonder what would happen if you put a sausage or something in there?

[@BrynosWorld]

Also, maybe paint a couple small pictures and see if it dries faster in the vacuum chamber.

[@skurczybyk12]

Do it with a sponge, bubble chocolate, strongly shaked can of soda (i wonder if the pressure from the inside of can will open it, since there will be no pressure around), inflated balloon...

[@StansTechVideos]

Does anyone else think the way he says vacuum kinda sounds like something Gru off Despicable Me would say 😂😂😂

[@rondeezy9746]

tennis balls, ping pong balls, basketball, balloons

[@TheTrumanZoo]

maybe two magnets in a suspension, and then activate the vacuum, i wonder if the magnetic suspension will be disturbed :) i hope you understand what i mean. :) two magnets floating would be cool, or a pump hooked up to a sphere maybe will be much stronger shape? does it get super col din the chamber? maybe a thermometer inside? would a vacuum in a vacuum work? a double insulation layer for the vacuum? would extra cooling (compressing the final contents during a vacuum even further?) help make more particles fall if you suck them out on the lowest gravity point of the shape? would electromagnetic blocking or shielding prevent new particles to enter the vacuum, like if we blocked light would this seal the vacuum leak to become almost perfect? (hope no implosion as a sphere is the strongest shape i think). i wonder what a normal watch vs a water resistant watch would do together in the same vacuum :0 and if a pc or processor would be well cooled or stops functioning in a vacuum, maybe a vacuum would super cool processors, or the heat generated could no longer escape well...

[@DJ_Dett]

You could try an empty 1 or 2 liter bottle (with the cap closed on it). The bottle should expand until it eventually reaches failure. The failure of the bottle shouldn't damage the container, and it might look interesting.

[@mikewest3108]

If you set the clock on foam rubber that would insulate the vibration much better. Put a whole, raw chicken in it! :-D Or maybe try to pop popcorn without heat. See ya next time!

[@tolipwen1487]

You might try to stick 'gauge blocks' together with vacuum instead of heat/friction. You could then perform a power lift to try and separate. If you do try this, prepare for when they separate to avoid injury. You could also try to separate stuck gauge blocks with vacuum instead of heat.

[@CatNolara]

Is there someone that puts random stuff into an ultrasonic cleaner? That would be interesting, too.

[@Fin4L6are]

Does sound get louder if you pressurize the chamber?

[@stabileseitenlage]

It will get this "underwater"-like sound.

[@Fin4L6are]

cool

[@Rolph777]

I guess it's time for Vacuum Pump Channel

[@vaska00762]

Deal with extremely dangerous "animal" in chamber.

[@UkiMalefu]

yes! this!

[@bricolagefantasy294]

make a clay animal with small ballon inside it, and watch it explode.

[@BlueStarGamingNate]

+Bricolage Fantasy2 that would be cool

[@conspiratordrew]

I came to the comments to suggest this myself

[@seth6082]

Yes, put a hamster in that thing!

[@Checkedbox]

can you also try over pressurising it?

[@robertr7923]

with hypr

[@marshalllaw123]

Do cheap ice cream! It often has as much as 300% additional air whipped into it, so it should react a lot.

[@Saragarhifighter]

Thank you for sharing your experience, please describe the brand and other configurations of the vacuum pump such as motor hp, rpm vacuum speed and ultimate pressure. regards.

[@Ts_Evildroid]

Awesome vids! Put some clay figures in there like you do on the press.

[@DanoninoBG]

Try Milka Lufflé, it's a chocolate bar with air inside of it.

[@eformance]

Correction, put a check valve on a bottle cap, then vacuum it down and release the pressure, it should implode the bottle very quickly and shrink it down a lot.

[@Xombie17]

Do a clay figure! It wall probably have an effect close to the marshmallows!

[@bricolagefantasy294]

if you play a lot with splashing water while pumping, you should consider putting filter so the pump doesnt accidentally ingest water. That will damage the pump, sooner or later.

[@RambozoClown]

After a few good pulls, you will need to change the oil in your vacuum pump. The oil absorbs moisture and other contaminants and you won't get as good a vacuum as with fresh oil. There are A/C vacuum gauges that will read down to microns.

[@solognabologna]

Maybe some sausages or cold cuts? Also maybe aerated chocolate or fruit slices,

[@TwoCraZyEyes0]

A balloon would be cool, with no air around it the Ballon should fill up the space on its own, and that would look sweet

[@dandroid3534]

please do a vacuum of, football, tennis ball, can of beer, superglue :)

[@stefantrethan]

I use the Testo 552 digital vacuum meter, it was the cheapest I could find that would measure the whole range I needed. You should make a clay beast with a "balloon" inside, maybe a puffer fish. Look at vacuum cannons with google, could be quite useful against very dangerous creatures.

[@jospi2]

Since it's European Football championship soon, use a fully pumped up football.

[@HydraulicPressChannel]

I have been thinking about that but if the ball breaks the pressure shock would probably broke my pump. So I need to do some safety measures before that.

[@bachaddict]

Start with a deflated ball!

[@imburrrito5945]

+Hydraulic Press Channel keitä siinä pastaa

[@tokus64]

listen up awesome guy, Put in some Oranges and Lemons. You could make some candy with this.

[@mikettt3]

I don't see any shut off valve on your vacuum pump intake. To keep from sucking the vacuum pump oil out of your pump, shut the valve off at the chamber, then shut the pump off. Unless it is some new fangled oiless vacuum pump with just some teflon seals or something. Then you'll just be worried about longevity. :) Like Ave says over there. Keep your slick feeling nice.

[@michaelaj4495]

What would happen to ice if it was vacuumed, would it boil or would the air bubbles cause and explosion?

[@Creepo11]

Also to make the vacuum lower make sure to use vacuum grease to properly seal all the connections and the lid.

[@PharaohFluidity]

Vac a bag of popcorn! (popped and pre-popped)

[@PharaohFluidity]

also packing peanuts

[@chumanho]

Try putting some fruits inside the chamber and see if you can produce some freeze dried fruits!

[@stefantrethan]

You should try lift heavy stuff with vacuum. Maybe make a competition who is stronger, your wife or the vacuum.

[@x0r1k]

Please put there bag of chips (closed). Also please try to put there one of your wife's clay animans. Thank you

[@skate50mph]

Bubble wrap? Could be interesting to see them swell and pop

[@qivarebil2149]

Did the sound really travel over to the vacuum pump?

[@zackeryfisher8440]

should do a light bulb since theres gas in it maybe it will explode? or the clay you make the animals out of with a marshmallow in it maybe a memory foam pillow or peice of one

[@StansTechVideos]

I think we need to start a new trend where we write 'have a nice day' on the end of every comment seeing as Lauri always wishes us a nice day :)

[@PuddinJr1993]

your also going to want to switch out your vacuum pump oil after every use otherwise you will loose efficiency. 2nd note there should be a gas ballast valve that will allow you to bypass the H20 en-trained in your oil at higher pressures (closer to atm) but you will have to close it to activate the 2nd stage as you pull down further

[@kenwolfe6093]

You must be a freon jockey. Nobody else talks about vacuum pumps that way.

[@PuddinJr1993]

once upone a time. ive been ammonia the last 4 years

[@kenwolfe6093]

+PuddinJr1993 I was a tech for 40 years......until I became disabled. The commercial side of the hvac/r business can tear you up!

[@PuddinJr1993]

i did a bit of res. right out of college but i didn't care for the company i was working for and they didnt care for me. Ended up working with industrial operators/maintenance. Much better. (sitting on youtube at 4am, waiting for relief)

[@DaylightRobberyCA]

After every use? Under what conditions? At the aerospace lab we ran pumps every day for years without changing the oil. Not saying it's right but it didn't seem to matter.

[@JasonW.]

if you get another go with water or alcohol in the vacuum, put in a thermometer to show the temp change as it is exposed to the near vacuum

[@mausball]

It looks like you may want to build a stronger vacuum chamber. The bottom is doing it's best impression of an oil-can bottom, and may fail spectacularly as a result of the fatigue at some point.

[@therealice]

Welcome back to vacuum pump channel

[@Traderjoe]

Also put a coconut or an egg inside it too.

[@robertr7923]

can you also compress in that chamber, that you pump air into it. if yes, put a marshmallow in it to see if it shrinks

[@robertr7923]

and use press for bigger pressure

[@hippopotamus86]

I doubt it would hold the pressure. It's a vaccume chamber which seals with low pressure, not the other way around.
