Today I will attempt to remove dents from metal using a hair dryer and some canned air. The theory is that if you heat up the dent long enough, that the molecules inside will expand fair enough away from each other to make the metal more pliable. The next step is to QUICKLY freeze the metal with canned air. If you flip canned air upside down, a freezing liquid comes out. Let’s try this experiment together. .

Bullshit, it should be good for small dent, not the holes like you make. Asshole
If the dent has strong tension, no..
You didn’t use plastic
Nah man I've watched this work with hairspray and a hair dryer.
Rip
Iron isn't made up of molecules. It's an atom. A single atom. The paint is made of molecules but doesn't really affect the density of the surface. Just staying, cause it annoyed me.
Do not waste your time on this video.
What The Hell i am watching
The dent you put in the items was ridiculous!! A bigger dent it's for small dents!! Not like it was smashed with a hammer 😂🤣😂🤣😂
that was just about the least 'scientific' thing i've ever seen! lol
the metal needs to have some "memory" to it, and you have to work it at the corners of the dent inwards, cooling the middle is actually counterproductive.
Cuz car bumpers are not made out of aluminum they're made out of plastic
It could work on scratches in car's color surface, but not in plain metal
If you push the dent from the inside it'll pop!
No no.. U need to place your fingers on the dent surface while its hot . Thats the magic
it doesn't work if the dent has sharp kinks. it's more for smooth bowl type dents. also works well on plastic fenders as plastic is more flexible and the loose atom composition. the trick is to warm it up but not to the point it is too hot. when you add the freeze you want a quick change from warm to cold, atoms tighten and return to the outer surface pressure. you don't want to go from hot to warm.
this works for pdc not metal dumbass
maybe you should have tried it from the inside
you shouldnt cool the middle, just the outside
Cars are mainly fiberglass so it won't work on metal…try that
u need to push from the inside
if that actually works what am i going to school for this then
leave the heat on longer
ils workin on plastic not à metal dud
pro-tip: buy a saturn.
I've seen my husband do this to pretty large dents with only a hairdryer
can this work on my social life
