[DimebagDarrel15]

[Goodlikable]

[vistigioful]

Invisible ink?

[iloveclubpenguincp]

You can use lemon juice, but this is a great replacement!

[CallMeAcoustic]

u can do the same thing with plain water

[Interwebz1]

Soy, 1%, 2% or whole milk?

[MrMathwizard12]

Will a sperm work?

[ElvishVegan]

Would soy milk work? I don't drink milk so there's none in my house.

[kevinjeet123]

hey,.,,,,, why to waste milk.... Instead of Milk we can use LEMON JUICE...... it is more clear than this....

[TVman154]

kewl

[tastetherainbow32109]

is that a dick???

[mweglhabx]

that was cool

[sizzlerboi]

can i use skim? cause i usually i dont drink 2% which i think you used in the video. i usually drink skim but i guess i could buy a carton of the forbidden 2% milk for this milky experiment. thanks scientific tuesdays, you give me so many evil pranks to do on friends tehehe! cant wait for seaon 2. yay!

[basketcasestudios]

would this also work with a hair dryer

[jacklyon100]

[LuluPiggy]

[Hacker010011]

[MatrixSniperz]

Because every secret agent carries a iron.

[xdie1337]

heh heh.. BROWN

[ironmango2]

No actually Ben franklin said "early to bed, early to rise, will make a man healthy, wealthy, and wise.". Not that milk thing

[marygrace1234567890]

i like it and everything but it will take to long to do.

[magicbuskey]

I thought it was the sugar caramelizing that turning the "ink" brown.

[OneSummerSky]

How do you tell when you're out of invisible ink?

[SkullzCandies]

the thumb looks like a penis ...

[TCreatorO]

you can do the same with pure lemon acid. Try IT!

[archrom1]

I love scientific Tuesday's

[undertaker9056]

you look alot like my science teacher.

[TEHCHOSENONE866]

you know whats better than an advertisement, an advertisement that WONT LOAD

[mrjshaun1]

Wouldn't that ironing a piece of paper make a fire?

[LinqPoss]

i threw milk on me but i didnt get invisible

[DroveThemInsane]

@LinqPoss We should iron you out anyway.. Just in case.

[LinqPoss]

@DroveThemInsane Just.. Dont try it.. It hurts..

[DroveThemInsane]

@LinqPoss Awww, you're no fun

[ihavemonkeysinmybutt]

@Onlyshadowdemon1 prolly google

[jabravideos]

wow

[vancer32]

ibangil ng ulo nimo

[ytje]

you can do this whit lemon juce too.

[pauldragusin]

is he filming himself in the bathroom?

[Combatgeek001]

WoW sucks Baaaaa@ls

[TheMollerTV]

the fat doesnt turn it brown, lemon juice turn brown and it doesnt have fat...

[divinegod102]

Lime juice works too, but with a hair dryer.

[Sinkatze]

@divinegod102 Or also put a match underneath and let the paper burn slightly, the message will appear, this methot with lime I think its better cause you dont want people having to iron to get them message. Hair dryer is ok too, but I prefer just matches or lighter since its something handier to have around.

[Simpsonsman120]

2270 people burnt themselves using the iron....

[glennsibz]

I would us that but Ive got a phone and the Internet for that shit

[RippedTornAndBroken]

can u use jizz`?

[domzilla90]

@RippedTornAndBroken Yup, i tried yesterday and it worked

[jedicoco]

[T2Mify]

i done this in school exept with a bunsen burner

[Gonamez]

Niice

[pyroisawesome]

now im gonna bring an iron to school....

[afedeeronel]

But wouldn't it be weird to take out a milk jug, write on paper, then get an iron, and then be all "AHAHA!" I'm pretty sure the teacher would be suspicious 

[JJlil1022]

good way to pass notes..

[BulbriosDomino]

I'm definitely gonna give a thumbs up!

[joejosephi]

i have exactly NOTHING to lose but a little paper and a Q-tip so i AM going to try it LOL.

[vireak209]

looks like you wrote it in crap? LOL

[tbh59]

dont pretend you didnt see that thumbs up sign....queer

[shaun0069]

Cant you do the same thing with some pee and a lighter?

[CordyBear1]

@shaun0069 Sure, if your pee is made of fat.

[EtsGeeBaby]

@shaun0069 yeah but thats disgusting

[ashi3june]

there's an easier way to this, use limewater to write the message, and put the paper under a torch/light to view the message.. its less messier, and saves the electricity :D

[kohrak123]

ooo! real james bond style :D

[MrChangingPartner]

That messages will smell :O

[EcstasyOfApostasy]

Just use semen. Worked great for the Brits.

[chadd990]

thumbs up if you've ever used this to send a message from prison

[Rushly123456]

=3 he drew a penis

[chrisofcolombia]

Actually, it's "Early to bed and early to rise" that makes a bloke "healthy wealthy and wise - not a glass of milk. Ben Franklin as I recall.

[maplemanfreak123]
