In this video:
The most abundant metal in the Earth’s crust, aluminum naturally occurs as a compound with other elements, such as aluminum oxide or potassium aluminum sulfate. As such, it was not isolated as a separate element until 1825 when a Danish chemist, Hans Christian Oersted, was able to produce a small amount.

Now that you know why aluminum foil is only shiny on one side check out this video and find out How Anti-Fog Spray Keeps Glasses from Fogging Up: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PLCWPfAREbA.html

2:09 they finally tell you why one side is shiny, one side is matte.

@CheeseTaterson 7 лет назад

I always assumed the difference was from when it's rolled for packaging, the stretching of the outer layer forced the crystaline microstructure of the metal into alignment, while the compression squished them into disarray. Thanks for the proper explanation!

@saintpine 7 лет назад

Is it a fact? I cannot come up with any logical reason why it should work, and I would feel quite silly even testing it myself. I suppose I could use a test method, cutting 10 pieces of paper before and after.

@arthurneddysmith 7 лет назад

saintpine -I tested it on a pair of blunt (not completely blunt) scissors, cutting foil around a hundred times. The scissors were still blunt afterwards though. Perhaps they were too blunt to begin with. Also, can help but notice the three commenters above you who are asking a question that was specifically answered in the video.

@micahphilson 8 лет назад

Watching this after top tenz is weird because I keep expecting him to be listing things! And if I watch it the other way around, it annoys me how there's a new topic every 30 seconds. But I love both channels! Why?!?!

@micahphilson 8 лет назад

***** There are a few people not even including the writers on either website. Basically, it comes down to the person who runs the TopTenz channel, the person who runs this channel, and the narrator who speaks on both. But yeah, it's the same speaker, maybe even editor. I think they should do a video highlighting the people working on them.

Pittsburgh, PA is famous for being the "Steel City". Up river is New Kensington, PA "The Aluminum City". Beside aluminum, New Kensington also gave use a more modern material: Kevlar. It was invented by New Kensington born chemist Stephanie Louise Kwolek in 1965.

@lfarquhar8081 7 лет назад

Thanks for the trick about sharpening scissors. Will try it!

@patrickhodson8715 7 лет назад

If this guy is British, why does the title say "aluminum" instead of "aluminium"?

@-yeme- 7 лет назад

he probably has a lot of american viewers, and americans react with hostility, confusion or both when they see anything they think is characteristic of other countries so he'd probably lose clicks if he put the I in. obviously he's not going to actually pronounce it like that though, he'd sound ridiculous.

@Markle2k 7 лет назад

+yeme You've got it backwards. The site and the scripts and the screen titles are written by Americans. Simon is the one who changed the pronunciation to suit his preference.

No which is why the government made aluminium cheaper. People stopped using tin so now the foil hats are useless.

@sushicraves 7 лет назад

Bonus 4 The lunar lander had a problem. The lander struts would be too heavy if a car strut technology were used. At the cost of $10,000 per pound engineers had to design a lighter onetime used shock for the lander. They knew a honeycomb structure was light and crush able but still heavy by mission standards. So they went with aluminum foil. It was light and can take extreme hot and cold. The foil was crumpled in a manner that when the lander touched soil it would support the weight and absorb the impact. The aluminum strut and foil cut the weight so well it paid for the cost of engineer design in all landers. even the few taken to space and moon and never used.

@Seldion 7 лет назад

@50srefugee 7 лет назад

My understanding is that Al foil must be rolled as two sheets back to back because there's a limit as to how thin the foil can get using a single sheet. After that point, it recovers its original thickness as it leaves the rollers.

@JVC7400 7 лет назад

For improvement, - It bothers me how only 20 seconds of this video has relevance to the title, when there are aspects about rolling that would be much more fulfilling to add to this video.

@AgtX999 7 лет назад

I thought it was so you wrap the foil shiny side facing the food so it reflects the heat back & the dull side faces out to not damage the oven by reducing reflected heat?

@mikepublic111 7 лет назад

I use the shiny side when I want to distract creationists.

@bloodandwinearered 7 лет назад

Which side goes up and which side goes down for cooking?

@sebimoe 7 лет назад

Does the shininess of the shiny side add to its insulation value from radiated heat? Or is the total reflected amount similar, just more diffused or not? Or is the matt side still shiny for long wavelength radiation?

@pirobot668beta 7 лет назад

The shiny side will reflect more infrared energy than the matte side, but only by 5% or so.

@1337fraggzb00N 7 лет назад

The real reason is: the shiny side blocks That Poppy from reading your mind. The dull side is just a dull side. Dull. Dull dull. Hurr Durr.

How are scissors getting sharpened by cutting through something that isnt as hard as the steel the scissors are made out of?

@JennieWrenStar 6 лет назад

So nice to hear you say aluminium properly.

@smnewstead4093 3 года назад

Aluminum only has one "i" in it. The original chemist who discovered it mistakenly called it "alumium" instead of the usual Latin so he subsequently changed it to "aluminum." The "aluminium" came as yet another alternate pronunciation after it had already been named. There are many British-isms which are incorrect, and even more American ones. The British spelling of "foetus" is totally wrong, for example; British just made that one up. It is "fetus" from the Latin "fetus" which means "fetus." Haha. Not enough space here to talk about the stupidity of Americanisms, though, but rest assured, there are plenty.

@vesman81 7 лет назад

@fetB 8 лет назад

Erm, how is the sharpening effect happening?

@Hamletstwin 8 лет назад

+fetB If you google it there is much debate on whether it works or not. I believe that the aluminum is just removing burs on the edges. That doesn't make them "sharper" but that could make cutting through some materials easier. The problem with that is since you are cutting through that thick of material you'll spread the blades apart which defeats the whole point of scissors. So your best bet is to sharpen them like any other blade using a whetstone. But some scissors you cant take apart so what I've found useful is a handheld sharpener. You wont get all the way to the handle but it'll help make those cheap scissors last alot longer. this one has been working pretty good for me. www.amazon.com/Lansky-3143-PS-MED01-BladeMedic/dp/B0085PPSIQ/ref=lp_2595201011_1_2?srs=2595201011&ie=UTF8&qid=1441123239&sr=8-2

@billysgeo 7 лет назад

So, is the saying "the food must touch the shinny side only" a wifes tale???

@carbon1255 7 лет назад

yes, why would that matter? Shiny out, it looks prettier.

@billysgeo 7 лет назад

Carbon 12 Before I knew the real reason for the "shiny side", I thought that the reason for one side to be shiny was that it was treated with some kind of lacquer to protect raw food from touching the aluminium...

@TiagoTiagoT 7 лет назад

Wouldn't the irregular side hold more bacteria due to having more surface area than the smooth side?

@billysgeo 7 лет назад

***** Probably. But why should that matter? Are you using it as a Petri dish? :-)

@TiagoTiagoT 7 лет назад

If the goal is preserving the food; usually you would want the least amount of bacteria on it. Bacteria are the main reason food goes bad.

@originalhgc 7 лет назад

OK, next question: does heavy duty aluminum foil, since it is thicker than regular stuff, go through the rollers in one layer and is thus shiny on both sides? I don't buy heavy duty (waste of money), so I can't go to my own kitchen to investigate.

I can't believe people paid big bucks for aluminum as if it were as valuable as platinum....(do Brits say platinium?) They must have had a rude awakening when they found a cheaper way to produce aluminum and the value substantially dropped.
