"Start by mechanically separating" *H A M M E R*

Teacher: *You haven't written a single word on your test paper!* Me: *Teacher, my pen is just built different.*

For those of you who don't have bulk Sodium Carbonate in your pantry: You can find a lot of it in special dry laundry additives, like OxiClean White Revive, which is almost completely sodium carbonate. Best household source. Hope this helps! :)

I like this more than my actual chemistry class, probably because he doesn’t give me homework 😂

A bank robber put lemon juice on his face because he believed it would make him invisible, so he didn't hide his face

I watched a single video about the plastic lining inside a coke can, now I’m absolutely hooked on your channel 😂

Him: Using Highlighters and Lemon... Me: Using the og WW1/2 method of pee and ovens...

My grandpa used to show me that I can write a letter with lemon juice using a quil (feather from outside cut at an angle) or a toothpick. Then we would light a candle and very carefully heat the paper and the message would show. Awesome that you can do it with a highlighter!

You can also just use lemon juice to write and when the juice is dried, just put the paper towards a light source and you'll be able to see the writing.

I only watched invisible ink in cartoon but it's now possible 😊🎉🎊

Mine fail forgot dry the paper now watching it again on bedroom laziness happening 😅

U r loved don’t give up on life

Fun fact: some dumb guy thought by rubbing lemon juice on his face it would make him invisible. He robbed a store or bank (I can't remember what) and was confused when the police found him so quickly.

thanks for this video! this will really work for like bendy stuff! thanks!

I really want to try this!!!! So cool!!!!

Drawing a boo with it was so perfect, this channel is great!

The only good DIY I have seen so far

Does any color highlighter work? Super cool!

Damn. Glow in the dark too!

That's really cool

Your shorts are the only ones I ever watch

I love your content, keep it up!!! Very wholesome videos.

Yeah I love it, "mechanically separate"!

Cool

Finally I can write two pages notes on single page

Best color ever. So futuristic

The Boo from Mario had me hook line and sinker!

That’s so cool 😍

Wow that’s awesome

Sp💀rm can also be used as temporary invisible ink. When it dries, it reveals the written text.

That’s cool & also can be used for coded messages

Lemon Juice alone is all you need. Heat the dried and invisible juice and it will reappear brownish.

Finally, an actual diy glow in the dark paint tutorial.

Ah yes, let me just bust out my sodium carbonate

That is awesome

lemon juice was the trick i thought from when i was a kid... (no highlighter ink) we'd write on paper with lemon juice with a Q-tip and then, we heated it over a light bulb to reveal the image as the lemon juice oxidized the paper and turned brown.

I'm gonna try this out. 😜👍

Amazing and wow 👍👍💵💵💶😲😊

THANK GOD I always wanted to buy invisible ink but i couldnt but now i know how to make now i can draw secret words hiding in my book! ALSO THANK YOU FOR TELLING ME HOW TO MAKE ONE THANK YOU!💜💜💜

Just like in National Treasure!

For the people who don’t know the ghost in the beginning was a “Boo”from Mario, they are only seen in the mansions or spooky levels in the game.

I remembered invisible link was use as a stamp onto your wrist when you go to Chuckie Cheese and you had to put your wrist under the black light to see your stamp.

It’s perfect for Halloween and Christmas 😅

Nice post👍👍

bruh I’m surprised if people couldn’t tell what was written just by the marks on the paper 💀💀

Nice ! Another acid works too ?

I did it and it turned blue It was very cool

A Boo from Mario. Awesome! 😎👌

very cool

This will be useful

WoW 🤩 Sir its cool 😎 In its work

I once did that at my kindergarten it was cool

This is going to be fun. 😁

Question, is reactive because of the lemon juice? Cool experiment.

I Will Try This Out.

The only diy glow in the dark liquid that I can actually do

Thaaankk youu ❤

This is too much work I'll just use my natural invisible link.

Your drawing of Boo was on point

wow my grandparents live on lake max! love to see culver on the internet 😮

youre my new scrinkly scrunbo, man

That's cool!

Does it work all markers or have any preferable one?

that's cool

yep im hunna do this with my daughter this afternoon Yellow is her favorite colar we have thepens lemonjuice and both baking powder and baking soda. thanks again 💯🖖⚗️🍎🏆

Cool 😎

After reading Devil In The White City in high school, I’m actually so excited to see this play out in a game

Thanks now i can put back the "invisible ink" into my pen😂

You just gaved free tutorial to highschool kids that understand English on how to make ultimate cheat sheet during the exams.(only they need is to find a small lamp with black light on it to attach it on the end of the pen subtly).

Bruh, that's cool

Nice

You can also jus draw on the paper with the lemon juice let it dry and then put it under heat to reveal the message on it

Cool.

Pee works as well, I saw it in an episode of locked up lol

Good to know, I'll keep this in mind for finals

Easier solution: I just have a clear marker and a marker that turns into a different colour when touching the clear marker.

Or just use lemon juice on a qtip and draw something. Apply heat and voila

Also makes a really tasty lemonade if you drink the second step

Liked for the BOO appearance 👻

I remember when we just used lemon juice. Oh I remember when highlighter pens were the cool new thing.

Hey no way, you drew a Boo!!

Uhmmm this is awesome 😎

Cute🎉🎉🎉❤

+1 sub for u

We used to write with lemon juice and iron the paper to reveal it so the text becomes brown

Super

Wow that's interesting 🌹🥇💥🧚🏼🧚🏼🧚🏼❣️

B O O M 🤯💥

Does this experiment take uv light or it can be visible in normal light

I learned this from bill nye

awesome

you can make some with apple juice, extract the juice, write with it and heat them to show the ink.

Can we use lime instead of lemon juice?

"My last two braincells be like " Nah nah we aint doing that today we ain't doing tha-

just write using pure lemon juice. once dried, iron over to make it appear.

How does it work? I’m guessing the fluorescein from the highlighters is creating a citrate salt with the citric acid from the lemon which may have different properties but then forms the free base again when reacted with the NaHCO3

someone tried robbing a bank using this method thinking it truly made them invisible.

Gravity falls fan trying to make a secret book:

Yeah i actually redid this one by accident heh😅

You may extract The Ink with 10 -40 vol hydrogen peroxide,It will also become invisible and It wont make The Ink sollution rancid over time
