Frankie Hobby : Only one question left: What's the purpose of this video?

Bryan Miata : I have so many more unanswered questions.. What are the little pull tabs for on the top of soda cans? Why do houses have roofs? Why do some people store air inside of tires?

02091992able : really nobody knew what the bump on the f and j keys are for? Its one of the first things you learn when learning to type is because that helps you find the neutral spot to put your hands more importantly your index fingers when typing without looking at your keyboard.

シリアルボックス麥片盒 : “Blue and white eraser” shows red and blue eraser

Kata Reddy : Your headphones and aux cables work because of rings. Your fingers would bleed without cuticles. Mice eat your notebooks. Soda bottles and caps are made for soda Keyboards are made to type. Backpacks are used to hold stuff. Whatever you want, really. Dafuq is a Chupachups stick? Oh, don't decapitate your lollipops. Your pens need to feel the breeze too. Fancy colorful eraser for your fancy paper needs. Mystery of the lazy underwear stitching Your jeans can't fall apart while you're casually sitting Wire that makes no noise Bam. You're welcome

FreeFromWar : I clicked for the ass in the thumbnail

B D : Fascinating I learned a few things I've also noticed and some of the comments for extremely judgemental not everybody understands everything or gets everything the same way as you do stop being so judgemental comments sit back and enjoy the ride and learn something maybe someone else will learn it too

Flavia Pitariu : I only knew of the ferrite core but none of them were shocking. They were very interesting

Rick Frick : I ike the soft inner lining underwear. Thats a nice pocket for your smartphone.

Teodor Galit : this is "12 Things Stupid People Didn’t Know The Purpose Of"...……..

Siberian Husky : ... you are incorrect with the first one... One ring - mono Two rings - stereo Three rings - stereo plus a microphone

John Dickinson : not studs, rivets!!!!

RAW TOPSHOT : Omfg... Is this video aimed at 5yr olds?, or is the worlds population really as thick as this video producer implies by way of making this video?

Kaila M : I always thought the pantie pocket was there so your lady bits arent rubbing against the seams

Don Javis : Watching this video makes me worry for the future of humanity, if people are So So stupid that they didn't figure this all out at the age of like 5 by being inquisitive or reading a book, the fact that you made this video proves that people are getting more stupid. 😋

TheLookatit : 6 07 is the underwear part

Mitch D : Allow "oxygen" into the pen? No, dullard, it's to allow atmospheric pressure to get inside the pen. No hole, and you'd have no flow due to the vacuum.

Flor Hoorebeke : yeah ok, I have to correct you on the very first, the jack with the rings. it is indeed left and right ear, but the third one is not the groundwire, it has multiple purposes, it can be a data wire, but it's usually for the microphone. for data it would be a digital display with forward, backward, stop, play,shuffle, random, repeat, ....and so on, but I suppose it can be ground too... I just stopped the video to write this, so please tell me you're not as basic on all other things???? I hope not, who knows, maybe there is one that I don't know off yet... I like to know everything about a certain thing, not just something...but I settle for something until I can discover the rest on my own...

allan harville : fun fact: Levi's rivets were once put at the joint of the seams in the crotch of any pair of jeans, they stopped doing that when people started to complain of the rivet getting hot when they squatted down next to a campfire !! Talking about a hot pair !!!

Sexy Pube : Who dat on the thumbnail because she thicc

Rosemary Williams : this was very useful information😊

M W : Poor form Interesting Facts! Was it necessary to prominently display the inside of a soda bottle lid that said, "You Retard"? Could a different soda bottle lid have been used? Using a serious medical diagnosis as fodder for video content is deplorable.

THE MAD AUSSIE BUSHMAN : I only watched this video because of that fine ass on the thumbnail!

Harry Irvine : The hole in the pen is to allow AIR to enter not just oxygen. You should be worried and ashamed if you didn't know the function of all of these everyday objects.

Stinky Cheese : That moment when you realize the younger generation may not get much past this level of technical detail in their lifetime.
