Scientific Tuesdays - Removing dents with a hair dryer?

Pukupelle Says:

Apr 6, 2012 - I never said that he couldn't comment, I just used his own logic of "if you once fail on something, you should never be allowed to do it again" on him.Off topic: And there's a question mark at the end of my sentence, which means that it is a question, making it hardly possible for it to be a statement.

Apr 8, 2012 - You'd think it would work better on small dents because of less energy needed

lacrossplaier55 Says:

Apr 8, 2012 - hey guy, the dent cant have a crease in order for it to work

Burnitnow567 Says:

Apr 9, 2012 - who wants to undent a paint can anyway? The force used to make the dent was more than the force created by thermal difference.. try more heat first or use less force on the dent or use an actual car door at a junk yard, then you can say with more certainty that it failed..

Apr 11, 2012 - try it on a car dumbass

Apr 12, 2012 - Except for the fact that he said that it might and cold work on "small" dents on "softer metals" such as the difference between a tin can, or a steel bowl, and an aluminum carthis was more a test of the theory of why than the fact it does work, because there is plenty of evidence on youtube and what not that it does, but not because of the reason most people think. it's not the dent popping back into place it's the other metals contacting and pulling the dent out.

Apr 15, 2012 - You spray around the dent dude, not on the dent -_-. The expansion occures along the outside of the subject not on the actual dent itself, and this is what causes the metal to warp. Its possible, just revised your strategy

Apr 15, 2012 - That was stupid how do you expect to heat up metel that much with a HAIRDRYER you need a heat gun if you plan on it doing anything

techdude154 Says:

Apr 16, 2012 - What about a blowtorch

Apr 17, 2012 - Co za jełop!

Apr 18, 2012 - *caugh *caugh was *caugh *caugh

wildog47 Says:

Apr 18, 2012 - Possible but with a greater heat source

UnstableAdrianHD Says:

Apr 19, 2012 - hey H-H it only works on plastic bumpers and who ever said a hair dryer probably was watching a tv show its a heat gun look about the same you apply the heat from the heat gun over for about a good 10-15s keep an eye on it then take a mallet and apply force not too much then presto... i know this because of my learning experience from my father :)

Apr 24, 2012 - dude that cough sounds pretty bad, you should take some antibiotics or something, i wouldn't want you to get a throat infection.

MrZangetsu1993 Says:

Apr 24, 2012 - what i also want to know is, why would you TRY and fix a car dent when you can simply take your car to a PANELBEATER which will only cost about a hundred dollars and you are GUARANTEED to get the door fixed and the door wont be damaged in any way, but if it is you can just sue them or tell them to fix it properly without extra cost.

Apr 24, 2012 - Pointless video. Comparing a vehicle's sheet metal--stretching over several feet and having a small area of that surface area indented (but not to the point of creating a crease or seam in the metal) to a hand-smashed empty aluminum container has to rank up there with apples-to-oranges. Maybe if this quasi-scientist depressed a golf ball into the side of a larger aluminum can JUST ENOUGH to be a noticeable indentation, I'll bet the heat-to-cold process would have worked just fine.

Apr 30, 2012 - that's like asking him if its possible to split an arrow with another arrow and him trying twice and saying "maybe i just suck"

JonnyRay82 Says:

May 2, 2012 - Why not try this on a car!? A frikkin can or bowl?? You are a fail.

May 13, 2012 - Where u the worst student in your school or what!

cegon2002 Says:

May 17, 2012 - works only on thin metal surfaces

austingurley1 Says:

May 19, 2012 - you creased the metal you tryed it on. it works on bowled dents smaller dents. without a crease or on a body line.

ksmmayhem Says:

May 27, 2012 - it has to be with a heat gun... heat gun produces more heat... hair dryer produces less heat than rather the heat gun itself... do research..
