Scientific Tuesdays - Removing dents with a hair dryer?

[SUPERJJMJ]

Use dryice on a warm day

[conbeter69]

use a heat gun forget about that hair dryer

[Jaundriss83]

@conbeter69 exactly wat i was thinking...ive done it myself, higher heat is what is needed...45 seconds with a hair dryer is not going to do it

[jamestbfraser]

I think that was a steel bowl - aluminum is too brittle to bend like that and not break, plus aluminum doesn't shine like that bowl did

[af1king2012]

you use a heat gun retard !!!!!!

[stavrosdra]

It's different to experiment on an aluminium tin/can and a car door.Your experimets were like a door or a bump is totally deformed.For smaller size(tin-can) you should give less pressure.Simple maths and physics....

[fartigus671]

@3:38 ?? okay!!! : there you go

[TheSolidpillow]

u could just use a plunger

[MrZangetsu1993]

just use a heat gun or welder instead of a hairdryer and use liquid nitrogen instead of canned air

[moreno747]

maybe on your fat ass it works.!!!!!

[eatsleepandskate1]

have you tried more heat?

[MrDhandley]

Wrong wrong wrong. It's not just about the size, and in your case the dent was huge compared to the tin, but it also has to do with which part you heat up the most, and then most importantly which part you cool down. Cool down the edges of the dent (the perimeter) not the centre.

[hawaiisnocone]

Maybe this would work on a soda can...

[nightsurfer1]

Your tests failed..... Your logic failed. Take that damn lab coat off, you don't deserve it! The thin sheet metal on a car door, for example, has a rigid frame that it sits on. That frame, in small way, helps pull the dent out as you do your hot and cold treatment. Next time use a coke can and weld the two ends to a solid frame. I bet it will pop out then. Size of the dent matters. Your dent on the can is equivalent the whole door being caved in......test failed... Class dismissed....

[MrZangetsu1993]

@nightsurfer1 it wasn't his logic he was just doing this experiment because people had asked him if it were possible

[rdeasybutton]

@nightsurfer1 u so mad bro.

[kookeekwisp]

@nightsurfer1 :)

[DivineFlamez]

@nightsurfer1 dont need to be an asshole

[darkblaze568]

@nightsurfer1 bitch

[ObliteAbyss]

@nightsurfer1 Get off your high horse, he even said at the end (which I doubt you watched, because I'm assuming you only watched until after the paint can) that it's entirely possible that it might work on a car. And something you forgot to mention is, thickness of the metal also matters. That paint can will probably have thicker metal than a car door does, a thickness which will also scale up to match sizes.

[ChrisHansenism]

@nightsurfer1 I've done it to my car, fuck off.

[waxonize]

Or take it to the car dealer on the way to the store to buy compressed air...

[wolf73663]

hey just tried it works well but just use the hair dryer on its own and use your thumb on the other side with a cloth over your thumb to protect it from the heat.

[TKeityan]

Dude, unless your car is made out of the same material as an aluminum can, your tests fail.

[702jordan1]

1,999 people tried it and failed, 7,508 tried it and was successful.

[SomeRandomDave]

''WARNING'' Don't Use A Heat gun , The paint will Melt like butter ....... wel thats what happened whit my Lada................

[membland]

You creased the metal, not gonna work

[MrYoutubillionaire]

where did you get canned air ????????

[princemoe415]

why do you need a hair dryer WTF

[perrolok100]

your dumd as fuck it does work

[DaRkLiGhTnInG165]

1988 people made the dent even worst than before

[cootercope]

bet it would work better with a heat gun instead of a hair dryer

[supermariohunter2001]

1 ? why do you need a bigger dent????????? PLEASE REPLY

[4G63PWR]

You creased it you dumb bastard :(

[TheKwisky]

I don't think that this is a conclusive test and I'm glad that you awknowledged that. Like other people have mentioned, the dent shouldn't be creased and a larger scale test might get better results.

[TheWhatever356]

mythbusters time

[mymomrocks8]

You should try using a heat lamp instead. Obviously you would have to wait longer than 45 seconds, but it would work a lot better than a hair dryer.

[midmob2]

This trick will work. I'm studying collision repair right now and have used this technique many times to fix the 'tin can' syndrome over worked metal can get, however it requires much more heat then a hair dryer can output. We use heat guns and rag soaked in cold water when doing paintless repair, however this usually leaves the metal wavey because the metal has been stretched by the dent then shrunk. To completely repair, it requires a oxy-fuel torch, cold rag, filler work, and repaiting.

[eddson11]

@MePeePeeInYourCoke You cant just pound out any dent.

[K4LI4NY4]

cars aint made of tin or stainless steel

[tiggerjayeward]

cars arent made of metal

[pilottoaster323]

some cars have plastic bumpers

[Mitchjl22]

just buy a fiero. No door dings for life. Whole body is fiberglass ;)

[jimba2000]

this guy is a bonehead

[SukmadikHo]

Try it on ya caa! Duh!

[Eringuy13]

what about a plastic bumper?

[olivera182]

Would deodorant work as the compressed air?

[iphoneksa]

Iron must be the largest area for heat expands and cold shrink

[nyballer322]

throw a baseball at your neighbor's car side door, then re-do steps 1-3. It works bro.

[TheMajood1999]

@nyballer322 lol

[moparman85]

The hair dryer and air can does work! You cant dent a can like the way this guy did and expect anything to happen. I laughed pretty good, and when he had the dent on the bowl and thought his hair dryer trick would work,i almst fell off my chair laughing. Anyway, i seen it done. if its a mild dent, where it looks like you can pop it out from the other side, just cant get to it, it will work. You can find it all over youtub. Not being mean, just informing everyone.

[kengkongs]

if someone dent my car i would need a really big hair dryer than...

[Mav3n1]

Or a dent from some asshole on Halloween throwing an egg at your car

[jim55rocks]

cars are not made of aluminum or filled with paint..

[FlyingDonutsMusic]

maybe if you used a heat gun instead of a blowdryer... but i garuntee tht will also melt the paint of your car

[1997sez]

where did you buy the lab coat??

[yousefsofi]

USE GALLIUM



[scialabba81]

It only works on plastic wow

[ducttapedood66]

a small ding

[tuning944]

U sayed u have a little succes on this? U haved NO succes Fuck You

[gluedtothemouse]

@tuning944 no fuck U

[shavacid]

There are two types of deformations "plastic and elastic"

when you have a dent with "elastic" deformation this technique can works but if the dent have a "plastic" deformation you’ll never can repaired with this technique...

Regards...

[jennypenny812]

it is not gonna work how you are doing it since both of those dents have creases it has to be dents without creasing so it will pop back... it would be more a dent of someone sitting on your hood and leaving a small dent or so... no creases!

[DAVIDx41]

and a small shallow dent like that caused by hail?

[denverdent]

I've heard that popcorn works too.

[denverdent]

um, that bowl is stainless

[mcwario13]

@denverdent zinc plated or annodized

[meggie590]

U have to spray quicker

[KewlKat143]

Come on guys. Do you really think he'll dent his car for just a video? Anyway, he's just trying to help.

[Shiggitydiggityz]

Nice to see this guy has no idea what hes doing or how it works. That and theres multiple videos on youtube of people doing this and it working.

[henryloco5]

#FAIL for scientific Tuesdays. yous are pretty dumb to be "scientists". This is for cars, and it does work. also, your supposed to spray around the dent, not directly on it. CANNOT be creased.

[Specter2x8]

Fuckin retard thinks he can cure the largest fucking dent with a hair dryer and a can of compressed air. Try a tiny, realistic dent you moron. Gosh this was so unhelpful.

[612miois]

You should try plastic, like on a car bumper.

[ilikestuff6619]

Dent cant be creased

[iPhoneAppReviewer]

Some asshole fucked up my front fender so I'll give this a try. I already have a heatgun now I just have to get a pack of compressed air cans which I need anyway to clean my computer case. I'll post the results when I'm done.

[tetsukun]

you have to use a heat gun... try that...

[xBigxWillie125x]

Maybe use more heat to heat the metal up more

[DaGunaholic]

BUSTED!



[roskipolski]

you souldnt at least have tried it on a car door?

[kisstheelf]

Have you tried with something made out of steel? That's the kind of metal used to make cars, so maybe you'll get different results that way.

[XSevenSonata]

Using a can and a bowl for reference instead of car is inaccurate. That's like washing your hands with peanut butter instead of soap.

[haimynameisnick]

@XSevenSonata depends on your car, not all cars use the same metal. i could see that can being similar to the outter metal on a door

[XSevenSonata]

@haimynameisnick Yes. But different densities, Different possibilities.

[THExXKuBa]

@XSevenSonata Actually you're wrong. He was correct in using those because their chemical makeup is similar to that of a car. You, sir, are a blithering idiot who seeks some form of gratification through commenting falsities on scientific videos. Next time, think before you post. Thanks.

[XSevenSonata]

@THExXKuBa Don't be so ignorant. I'm aware that a paint can's material is similar to a car's. However, It's "similar". I said inaccurate, That doesn't mean "false" Results could be "slightly" different. Nor was I faulting him for using a can instead. Sometimes you have to use what's available if the real thing isn't present, That's understandable. Besides, Each viewer has every right to choose they're own path. I'm in no way trying to mislead others into thinking this method works.

[Megadoomable]

@XSevenSonata Yum... Peanut Butter... Too bad my grandparents don't like it...

[planktin91]

@XSevenSonata metal is metal.

[XSevenSonata]

@planktin91 Lets see you melt a tin can with a match, While is possible for an aluminum can. Yes, Metal is metal. However, Different densities, Different benefits. Not all metal reacts the same.

[ijtl999]

@XSevenSonata the point is that if it cant work in small things, then it wont work in big things. It would be stupid to try it at a car then find out later that it wouldnt work

[XSevenSonata]

@ijtl999 No one will know that for sure unless they try. Just because the method didn't work for him with a can doesn't mean it won't work for a car. There are other small aspects to look for such as type of car, paint, and size or angle of dent for example. And as I said, I know that sometimes you have to use what's available if the real thing isn't present. It's pointless for many many users to continue arguing of this, Any further ignorant replies will now be ignored.

[animegirl121628]

2:46 hehe funny



[how2macc]

what if u use ice instead?

[mgh6x37]

This isn't working for you because the can and the metal bowl are both thicker than a cars "skin" as they call it.

[joyride199]

I think you're trying it on harder surface .-. The car is body is made out of plastic, that's why it comes back out. 

[KaylinJH]

it works far better if you do it in reverse

[mrfluffy117]

The reason yours ddnt work is because your suposed to do it repededly. Plus the stuff u used isnt what car fenders are entirely made of, you have to take into concideration the paint on the surface as well. And your suposed to tap the surface around the dent with your fist a few times. ive done it with my 88 trans am Gta and it worked wonders for me

[johngorgis]

You need a heat gun not a blow dryer

[fezants]

You did it all wrong...! spray it around the dent, not directly on it...!

[coolbasith]

try again TEEHEE

[iRobii]

I was pissed of at my mom and hit the fridge with my fist. I regretted it as fuck and now there is a dent on it.

Lets hope that this works :(

[Hidden2BHeard]

@iRobii Did it work lol? Just Curious

[iRobii]

@Hidden2BHeard Well it didin't. But it worked on other dents just fine. It kinda pops out so I suggest that you try it

[zobya97]

you should do more scientific tuesdays like this, it's like mythbusters

[1cspr1]

I never realized cars are made from aluminum bowls and cans

[Hidden2BHeard]

@1cspr1 Well they are made from the same type of metal...

[eagletalonpl]

small dent you fatasss

[claudiu222]

idiot!!!!!!!!!!!!!!!!!!!!!!!!!­

[bendaviskate]

1:00 Nice and Denty.....

[polla2256]

You creased the fuck out of it only a tard would try this method on a creased dent

[C0mm3n]

I just vomited cus your fat face makes me sick...fat boy

[PheodasDraconis]

If it did work, without an extension cord how exactly were you supposed to get your hair dryer outside?

[ronald67601]

el resultado es fallido en sus pruebas por que los recipientes son muy pequeños para que aga efecto y tiene que ser en un area mas amplia. pruebe en una oja de lata de un metro cuadrado aproximadamente y se dara cuenta

[jeremycat05]

i hit my car with a baseball bat on purpous and tried it

it didnt work:(

[cebolla4015]

Its not possible just not probly on a oil can on a fender try that

[mjeatsies]

you need to heat it for longer

[fartingonyouwhore]

In stead of cring like a bunch of babies go find a whore to fart on

[gideon001]

@fartingonyouwhore I'm a certified collision technition and i approve of this message!

[Whitews6transam]

Ive seen it done on a car with a softball size dent on a ford quarter panel and it went pa popped right out. It cant have a crease or it wont work!

[junpower010]

@Whitews6transam

correct

[luxmar1]

@Shadowbangg U MAD BRO?

[junpower010]

@luxmar1

Don't worry about that trollin' fatty 16 yr old who thinks he is the coolest DJ in his garage and plays "Maple Story"! LMAO

Just check out some of his uploads and you will know what I mean. lol

[Shadowbangg]

@junpower010 Well how about "Junkie" (from your page description) like you just get off the internet & quit hating on video's and people, all you do is mess with a car... You can't judge other people for no reason. & It gets quite annoying, if you try sending me another hate message i'll just ignore you, if you aren't hating on me ( & other people) then it's fine to state your oppinion. You could've said "I don't think you did this right, because you can remove dents with this method."

[junpower010]

@Shadowbangg

This coming from a 16 yr old DJ who plays Maple Story in his garage!

Stay warm in your garage Troll boy! lol

[Shadowbangg]

@luxmar1 No, i'm not mad because not what everyone says is true, if people wanna lie about me, or hate on me they can, but when other people see who i am they'll see i'm not what the haters say i am.

[jonathan0020]

HEAT GUN AND DRY ICE!!!!!!!!!!

[Caleta280]

Moron on the loose.

[Shadowbangg]

@Caleta280 Haters go home. We don't want people like you here.

[junpower010]

@Shadowbangg

Trollin'! lol

[shayyyl]

This guy is a moron , maybe if he actually tested a car door it would work not an aluminum bowl or soup can ; "double idiot"

[dark1blade11]

try using fire other than the blow dryer that might work

[Panino4life]

terrible video

[shadow1058]

Kick the person's car for revenge?

[Nerv1503]

Gay

[allanngo]

What if the dent is on the roof of the car? How do you flip the compressed air upside down?

[Nogorn]

bigger dent weaker metal... soda can?

[DaftBoy891]

on the bowl it kinda actually worked just that it flattened instead of rounded

[LukeBillwalker86]

Holy shit, that was stupid.

[lifeindawild]

Where are the mythbusters when you need em?!?! D:

[kausik47]

@lifeindawild ya i din watch mythbusters from ages do they still make them shows

[SoSikhOfWeSikh]

no someone cannot dent my car with their hand

[VideoPolicePatrol]

You make your self sound dumb, it works on smaller dents. And when heating it, don't just heat the middle you have to heat the edges too. It worked great for me- it's worth a shot for a $5 bottle of the air duster and a hair dryer then a $100 body shop fee

[ksek09]

lol this is the prime example of a youtube scientist. he watches videos and videos and videos and thinks he's an accredited scholar

[michaelovitch]

As i know there are only atoms in the metal.

not molecules.

[KCRskidder]

This method DOES actually work on small dents on fenders, ive used it many times

[jmwwd]

@KCRskidder So exactly what did you use, where can you get everything and how much do you think everything cost?

[kcjmmmzzz]

Dumber than John Mccain. Try it on a small car ding you idiot. Who wants to repair a soup can anyway?

[ilovepie6647]

Yo!! dumb ass.Car bumpers are made of rubber.plastic,and composite material.Todays bumper is not your grandpa's all metal bumpers.The only thing that you've proven is your....an ediot..dumb ass.

[BMXrideforlife1]

@ilovepie6647 your an "ediot" idiot.

[BMXrideforlife1]

@ilovepie6647 you're an "ediot" idiot.



[pegstir]

if you have a dent in a ping pong ball a hair dryer WILL fix the dent just try it

[mrfunnyboyz1]

you should add another day for scientific tuesday so there can be two episodes every week! thumbs up if you agree!

[jamiebarnes111]

It only works on cars because of the way the body is manufactured

[scootyify]

@jamiebarnes111 your an idiot

[laloho]

Estas bien pendejo chavo did you know that there are different types of metal?

[Demondealer09]

Its not working because ITS CREASED!!

[MakBlower]

IT WORK TRY TO SPRAY TO THAT POPS OUT IT WORKS!!!

[HelleRita]

maybe try it on iron instead of a tin can and aluminium?



[realcampusman]

this video is LAME, FAKE, and a TRIPPLE FAIL

The hot cold molecule therory only works if there isnt a large crease stopping the action. we learned this basic info back from mr. wizard

[realcampusman]

this video is LAME, FAKE, and SHOULD BE REMOVED

The hot cold molecule therory only works if there isnt a large crease stopping the action. we learned this basic info back from mr. wizard

[ItsBrandonNow]

It would probably work if he did small dents like little dings

[geolegg736]

he hit the bowl with a hammer

[zobark12345]

like if you were wearing headphones then the fail part scared u

[kyzerSieg]

guatón torpe. Esto es para hendiduras pequeñas, no para aquellas que deforme mucho el metal. Es para lo conocido como deformación sin perdida de pintura

[wtfallusernamestook]

your are a fail try using it auto body, not the fkn kitchen

[JoeRickNo1]

The real problem is this. Once a forceful dent has been made in metal other than a cursory push/fold the metal actually expands so no amount of popping or even pushing it out from the reverse side works. Theres more metal in the dent area than at the start. Even banging the metal out increases the metal area! The metal has to be popped out and then "shrunk". Its a real damn bugger!

[thecargps]

a car?

[aequitas18]

what a moron! i don't know much about cars, but i know for a fact that all cars DON'T HAVE METAL BODIES!

[lank05]

next time just use dry ice on the dent. it works.

[MADDOG6400]

You did everything wrong. You can't remove dents from stainless steel like that!

You sir, are a FAIL!

[JohnMarshall5646]

This guyndid everything wrong

[MrShortdorks]

@clintmmartin that's great I've tried to share the scripture but I get nervous about war people would say but thanx soooo muuuccchhh for putting that on it means alot to me

[TomathyCricket]

Strange, I tried this on an a soda can with a cheap hairdryer and a can of spray on deodorant and it worked immediately and perfectly, even with a creased dent.
