How strong is a strand of hair?

[SupahLuzah]

he said brain 3 times at the start

[TheAniy21]

if your hair is long enough and you braid it, your whole body can be suspended off the floor and spun around in circles. circus performers do this

[mleeho]

did the hair actually snap? or did it just slide off the tape because of the weight?

[rxgeass]

yo the piece of hair he was holding looked like pubes

[SCBCWTB]

i wonder if a curly worly is stronger

[JoelOwnsJoo]

Another source of error, besides the tape, are the pennies. At a point in time they stopped making pennies out of pure copper, and used a more cheaper metal (zinc I believe). Too lazy to calculate the actual weights, but I'm assuming one metal is more dense than the other, and would result in heavier pennies.

[neopentane2004]

@JoelOwnsJoo see the whole video b4 commenting Einstein

[adrianehm]

You should consider the weight of the tape as well

[TheCompGame]

@adrianehm I know im late but he did consider the weight of the hair because he measured the total weight with the tape and pennies together.

[TheReelNeel]

need more fun channels like this.

[pennyjack2]

he has a boner at 0:18 too 0:29

[fang4643]

I used to do hair strength experiments like that all the time by pulling my cousin's ponytail. it never broke, and I pulled pretty hard sometimes. Conclusion: hair IS strong !!!

[KillerAnakin]

...Im guessing your single???jk jk i learned something new today..pointless but new

[Autoworst]

This video was the definition of the word "Pointless".

The strength of a hair strand depends on so many more things than you can imagine, thus the results of your experiment only applies to the strand of hair that you used.

[EchoplexTheUltimatum]

@Autoworst Agreed. It's like phonebooks. (ripping one phonebook at a time versus ripping two+ at a time)

[xsketcherx]

jew hair...

[r0bott360]

How much hair can a douche bag eat?

[francoboy7]

How is this suppose to be scientific ? Maybe the tape did broke.... not the air.... You are taping a hair with Tape.... the tape is doing something on "How strong is a strand of hair...."

[nachotee]

Although, the lenght of the hair would also be a really important factor as to how much wheight it can hold. (If i can remember the physics behind this correctly =p)

[SPS148669]

The hair of an Asian is the strongest as the AZNs have the thickest strands of hair of all races.

[Ripstik2010]

u guys r all noobs u go on you tube to learn

[afromau23]

cool not LOL =+)

[Castaril]

I think I have the strongest hair in existence. Its blond and poker straight, but it grows straight out from my head like a perpetual buzzcut. Its impossible to comb because each hair will bolt back into straight position if I try to bend it.

[daisy1903]

yayy!! this helped so much! I needed to know how I can measure the strength of hair based on exposure to chlorine... (8th grade science fair) THANKS SO MUCH :D

[jomokip]

o my gosh the penys are floting

[viewtifulethan90]

hey thats what i was gonna put

[Jarvie1414]

looks like a pube XD

[TheGtagunner1]

is experment your favorite word

[UrbanFantom]

no saying this is wrong but u have to think A. the tape has mass to and B. it also is how helthey ur hair is but thats cool

[misternash16]

1:33 looks like a pube

[wspang1993]

its not 25g, there are scotch tape there.

[WDW1993]

the penny is floating haha

[Pringlesplox]

he looks like shrek

[izidor]

my hair vs my friends lol xd funny

[DDRsensation]

hairrrrr......

[tossnturn23]

wow.. kids should watch alot of this thing these days rather than porno..

[thompsonarchie]

But I have learned so much from porn...

[TeenageIronman]

@thompsonarchie what do u mean?

[madness24680]

that means you need 17 strands of hair to handle the weight of a kilogram :P

[UnknownXV]

And we have hundreds of thousands of hairs! Holy crap, the hair on one head could support nearly SIX THOUSAND POUNDS!

Wow....

[zenthex1234]

our scalp would peel befor we can get that hair to break!

[GodsWildAnimalMom1]

cool I am so doing it now THX I subsribed COOL experiments btw :D

[AYOitseny]

Awesomeee.

[trollock]

omigosh! this is soooo scientific!

[jamenealm]

did the tape come off or did it just snap?

[Gulipad]

never mind, i didn't watch it 'till the end

[Gulipad]

what about the weight of the tape? ;-)

[BWEARS]

he weighs the 23 coins and the tape at the end... just skip towards the end

[VirtRampage]

hes freaking me out

[Draglx]

i loled at 3:05

[chidori0wner]

does anyone know the project title?pls reply by today

[dragonforceisasem]

i wanna become a scientist now =) i luvs this guy =)

[xxbwb24xx]

PUBIC HAIR IN YOUR MOUTH NIGGA

[Streetracer8998]

blonde, or brown, pubic, or head

[Wookiee110]

I have a lot of hair

[Jostein200]

plz

[Jostein200]

plz tell

soda

[mortenrobinson]

He weighs all the coins with all the tape in the end, so it is pretty much accounted for...

[dansut324]

fails to take into account the amount of tape. stupid.

[Opiv337]

if you watched it to the end you would see that he ways the pennies and the tape together retard

[Schizima]

Strong enough to bear your cum you hottie

[lorinrtard]

fake hairs stronger than that

[gmaster717]

so fake

[werealldum]

lol the pennies fell

[oooJOHNY000]

r u an actual science teacher

[iwanttodieyo]

wow triangular pubic hair?

they are curly

[GregH249]

I think a pubic hair would hold way much longer. It would probably hold a bunch of quarters.

[rocio89]

eww

[blagertimber]

what about a dick hair : P they are normaly prety thick and they are also triangular ;)

[JoeyPsych]

triangular???

Maybe you shud go to a docter m8, it's supposed to be curly

[happyblahblah]

lol.

[izamelina]

thats coOl!!

i am looking for a science fair experiment

would you suggest something interesting please?

[Core404]

I bet you the hair sliped out, didnt even break

[mattthemad123]

peice of sssssssstring

[randomcash555]

PLEASE DON"T KILL THE PENNY

[randomcash555]

For your mentos and soda experiment . . . I WANT TO KNOW WHAT HAPPENS, YOU TURD!!

If a little kid was about to die and all he wanted in life was to find out what happens and he HAD NO SODA or CANDY, what WOULD HE DO?!?!?!? OR............... what if you weren't aloud to drink soda? WHAT WHAT WHAT - I DONT HEAR YOU TALKING OOOOOOOOOOOOO!!sniffle sniffle. I still feel bad for the kids who's spirits you DESTROYED!!! THATS RIGHT!YOU!TOOK!AWAY!THEIR!SPIR­ITS!YOU!THEIF!

oooooo you theif!!!!!!!!!!!!!!!

[ExCandi]

O.O fasinateing

[Emi278]

wow nice

[alecd86]

he should try my pubes

[blastgirl98]

your such a perv

[joshmista]

lol

[IMrennie]

lol...this was cool

[cannabishead4420]

Holy shit

[acid1980]

not for u 2 feel bad marshall brain but it was funny when the pennies fell.

[frankyo75]

ZOMG FLOTING PENNIESZ IT BEZ MAJIKS!

[conypony]

Rofflesocks!

[christiney89]

did the actual strand of hair break, or did the tape holding the hair to the pencil give?

[eggsmelljr]

That's what i was thinking

[MarukashiX]

You can see that the tape was still on the pencil when the hair broke.

[natyangel343]

wat about the tape's weight?

[01kgunn]

He weighed the pennies and the tape, remember?

[vz2991]

Try pubic Hair =]

[Rayden440]

holy crap!!! if u have very long hairs and u stack many of them together i can have a fishing line!

[youknow566]

try balc peoples hair

[dodgedart74]

of course he wieghed the whole thing. because it took thew whole thing to take it down, dumbass

[DieInPeaceBish]

cool

[colleen3217]

I think my hair is thicker than his :D

[griffinrockslike]

did you think about the wait of the tape??

tape has weight too!!!

ITS NOT JUST THE PENNIES

[gearsfan999]

he weighed the entire thing in the end retard

[loperspest]

Yeah, my thought too, but he weighed the tape penny combination AFTER it broke, so it was a better test then I thought it was going to be.

[GoldenBoy64]

did you think of spelling WEIGHT right?

[dogsruleoutloud]

omg 23 pennies 0.0 nice job dude..

[Auginater]

what r u guys talking about?!?!!? This guy is my favorite utube guy

[jiveroxiv]

good...

[lincolnlog44]

fuck u kid

[Kickerinthehead]

no one likes you

[lincolnlog44]

says the illegal

[Kickerinthehead]

you mean like...illegal immigrant? I'm not even an immigrant. I'm from Maryland. Thanks, though, for noticing my tan.

[lincolnlog44]

this guy is a doeshe, get a life.

[AIphanoob]

it's a "douche" you douche

[zalvator]

it didnt break...the tape let go of it, that was pretty much a test of how strong tape is

[firemaiden34]

how do you know that?

[zalvator]

Cause i'm not stupid

[trupti58]

good work- keep it up

[JBar9891]

hair is indestructible it will never destroy. its only weakness is fire.cool:)

[RadSunglassesFilms]

Thats why they invented scissors.

[JBar9891]

you can cut hair but that dosent mean it is destroyed

[gabyrubi13]

HEY THIS GUY IS ACTUALLY COOL

[cadonuno]

lets make a new sport...

the "stronger hair" sport ^^

[hm123productions]

way too much time on his hands

g

[Worshipchirst]

nice

[dys4ikH2]

i feel ten times smarter after watching this

[Azilythe]

It's stronger steel I guess, because your blade dulls.

[will01r]

but the tape ways 2

[tonyart01]

Thank you for helping me with my homework!

[lunavixen015]

that's actually not quite accurate, the weight of the tape isn't put in there

[jot88]

haha yes it is, watch it to the end

[mynameeminem]

yes but it still wasnt accurate because he didnt account for the distance from the pennies to the penicil wich would have actually maade the weight heavyer

[russia21]

true

[footballkid9686]

not true*

[eatganj]

uh yeah it is, if u watched it to the end u'd know that

[lazyhippy94]

Darker straighter hair is stronger than blonder curlier hair...>:O hooray for pigment!

[rubysp]

So techniqually if someone grabs hold a handful of hair then it's able to withstand a person's weight? That's pretty amazing. Thanks for the vid.

[lazyhippy94]

The hair is...the roots holding it to your victim's head however..isn't

[rubysp]

ouch

[johnboyer777]

continued...

The polypeptide chains are in turn joined by side bonds. There are three types of side bonds: salt bonds, hydrogen bonds, and disulfide bonds. The salt and hydrogen bonds are most prevalent, but are weaker and are broken by heat and moisture. .

[johnboyer777]

your hair is approximately 91 percent protein, and is made up of long chains of amino acids. These chains are found within the fibers of the cortex of the hair. The amino acids of these chains are made up of the elements carbon, oxygen, hydrogen, nitrogen, and sulfur (are also the building blocks of the skin and nails) and are joined together by peptide bonds. Long chains of these peptide bonds are called polypeptide chains.

[rahul9211]

really jobless guy ..but good time pass for us

[highlander360]

hes a virgin

[B1NGLES]

this guy is amazing!! haha

[Awesomedude89]

Fake...Hair is made of dead brain cells, not Keratin...

[SoccerStar10ITALY]

dude i think this dude know wat hes talkin bout........

[freterollai]

everyone thiks that but it isnt true, its made of mostly protien like john boyer said above, just read his thing, if you dont understand it dont worry im leraning that stuff in ap bio right now and i still have a hard time following it.

[wilmpunk]

he sounds like tesco vee

[iamsteves]

you have the hair of champions

[BirdValiant]

You gotta take the tape into account too.

[purplegymshoes]

I was thinking the same thing.

[Iankap99]

he did when he wieghed the final prodect the tape was in too. after taping 23 pennies on it wieghed 62 grams. 23 pennies with a weight of 2.5 each makes 57.5 grams. 62-57.5=5.5 Thats how much tape was there 5.5 grams.

[phazonxl]

you suck, your using Suave or something

[darrenzx]

definatly a queer

[lnternet]

doesn't it depend on your shampoo?

[binkle1]

Thank you! Now my daughter has an idea for her science project! We'll even try our dog's hair.

[mikesdjftr]

or cause hes a dum blonde

[TenBruggencate]

nice video! this is a great fun activity for the kids. i wonder if different shampoos REALLY make your hair stronger or not

[gothreapersMOMMY]

my hair hold 20 lbs

[alex3ka]

bullshit! oh yea my hair can hold 35tons! beat that mofo

[NahChillYuBuggin]

What about black hair versus white hair?

[pyropunk07]

Well i could hold up to 54 pennys on MY strand, BEAT THAT BITCHES.

But way to go on the experiment, it's way totaly cool man. *tumbs up*

[M4sk3dC4sp3r]

are you sure the the hair dint just come out of the tape i held up 46 pennys with my BLOND hair!!!

[pro7o7ype]

1st grade science class?

[SLT23C]

very awsome video!!!!
