Time to make a video on homemade UV light to go along with this video!

[@blazeanderson2657]

Can you soak paper in liquid nitrogen to see what happens? Will it shatter like glass, will it still burn?

[@harshsomvanshi8963]

Blaze Anderson I don't think it'll shatter like glass, but it definitely will bend and crack.

[@eggrollsoup]

Harsh Somvanshi it wont bend

[@timvdp7460]

Blaze Anderson Nothing, if its solid it stays solid, it can't change its properties

[@TheBigRalph]

Timothy Vandeponseele Actually, i think it might freeze any water inside of the paper, so it may become brittle

[@mkstech7004]

It will breake but donot shatter like glass i think

[@Imtimmahler]

So if you soak a white shirt in bleach will it just look black under the black light?

[@renloris460]

Just to clarify, what you used was a dip pen, not a fountain pen. The idea behind a fountain pen is that it has an internal reservoir of ink, like an ink sack or interior piston, so that it doesn't have to be dipped. Thus the ink can constantly flow out (like a fountain) rather than being dipped every half sentence or so.

[@initialonyt]

Can you make ice cream with liquid nitrogen🍦

[@jairo8159]

[@alexandramaria9199]

He made a video of it

Initial Bricks they have. In multiple videos...

[@Raines_Railway]

Wolfie vlogs no that was with dry ice

[@kkay9598]

Y’all he made ice cream with dry ice and the ice cream with the dripping it into liquid nitrogen isn’t the same as actually making it with liquid nitrogen the ice cream was pre-made so don’t flame xd

Hey, I wonder what will happen if you put a spray paint can in a vacuum. It contains compressed air right?

[@HomeGrownPyrotechnics]

compressed butane i think

[@traashartist1576]

Use bleach as an ink? Nah man I'd rather use beach as a drink

[@kr4zyy]

I had an invisible ink pen where there's a black light attached to the cap, and the ink glows instead of the paper lol

[@Metzli]

I had one of those too, but the ink ran dry and the light doesn't work anymore xD

[@ampedup8309]

[@GregAtlas]

As a control, try using the quill without any kind of liquid loaded into it to see if the etching may cause a darkening effect from potentially thinner paper where you wrote.

[@ljubex]

Idea: Can you refill an inkjet cartridge with the bleach (or the other stuff) and try to print something invisible? :)

[@LUXRAY_97]

Directions unclear, accidentally drank bleach

[@twent1one]

Is u ded bro

Its possible

[@benasm2677]

you can

[@elias_bauer]

You can if you refill the ink cartridge

you can. use old catridge and make a hole on top of it. use syringe to inject the baking soda. i think....

I think the baking soda grape juice one is just a simple acid base reaction maybe try it with dye added to vinegar

[@brandonriggs1808]

what happens when you put a glow stick into liquid nitrogen

[@wibbly8011]

Hey just quick terminology thing from a fountain pen enthusiast, your pen is a dip pen, you can also call it a quill because of the feather (I think). It is not a fountain pen. Fountain pens have a reservoir of ink which is drawn through a metal nib via capillary action.

[@Imtimmahler]

“not bad.”

[@jakes1521]

Make a wind turbine to generate electricity. You can use magnets and copper wire to generate the power.

[@benkelsey891]

Awesome video! Though on a semantic point, that wasn't a fountain pen, it was a dip quill which is an older design. Fountain pens have the ink contained within them and can be refilled from a bottle.

[@sabers31skip35]

You have a beautiful hand writing!

[@ConanRider]

Would be kinda cool to see if you could put one of these inks in a real pen. You could try to fill up a fountain pen cartridge.

[@purtalpro6789]

What happens if you boil polyethylene glycol like if you wanna see this

[@NomaanulHasan]

Invisible ink ideas was very nice. You can also try to use onion juice as well, similar way you used the lemon juice.

THANKS YOUU!!!! I GOT BRILIANT IDEA USING THIS INVISIBLE INK INTO MY CHANNELS

[@ImSlater]

Idea: Would a bag of chips become stale in a vacuum chamber.

[@jonyturbo1]

i don't think it will

[@beastmodegames2249]

No it wouldnt

[@beastmodegames2249]

They go stale because of oxygen

[@carpii]

bags of crisps are filled with nitrogen. we already know they dont go stale when oxygen isnt present

[@stevezep6750]

Triplex 1 HOUR - NCS will Soda in a vacuum chamber with mentos have the same reaction xD

[@HolyBits26]

Test if simple flashlight can reveal the secret message in the bleach

[@joeyveldink4902]

First, they take the dinglepop and they smooth it out with a bunch of schleem. The schleem is then repurposed for later batches. They take the dinglebop and they push it through the grumbo, where the fleeb is rubbed against it. It's important that the fleeb is rubbed, because the fleeb has all of the fleeb juice. Then a Schlameeh shows up, and he rubs it, and spits on it. They cut the fleeb. There are several hizzards in the way. The blamphs rub against the chumbles, and the klubus and grumbo are shaved away. That leaves you with a regular old plumbus!

Hey u should try what happens if u put a burning paper in a vacuum chamber

[@johnbecker3116]

[@MrDoboz]

burning candle in a very big chamber

[@YourSuizo]

MrDoboz It would extinguish, as there is no oxygen to fuel flames

[@MrDoboz]

with time, eventually. but I think the flame would be biggen than usual, as the pressure is lower, the flame won't get as much resistance

What happens if you pour liquid nitrogen into molten metal?

[@peppergames5268]

I think nothing will happen, the liquid N is way to light, to even do something to the surface of the metal, maybe if you throw the liquid violently, will make some splashs.

Thanks dude for a great video!

[@morganminecraftlegion9101]

Well, someone appreciated The Dark Tower. I personally didn't find the story all that memorable or well thought-out, but to each's own. One thing I can say positively about that film was that the rendering was done well, and I have no doubts that they fully animated those creatures (I forgot what they were called, the things that feed on fear, sadness, and anger: the primary human weaknesses) were made ground-up from cubes or spheres in a tool like Blender, as opposed to using somebody in a costume and darkening the resulting picture.

[@AngelDreamStudiosOfficial]

The way the lemon juice ink apears when heated looks like the marauders map.

[@DragonElf66]

I think the bleach works because the paper has special dyes in it to make it appear whiter. Under the UV torch, these glow a pale blue. The bleach reacts with them and stops them glowing under the UV, but doesn't alter the appearance of the paper all that much

[@sarahmulkey9603]

What would happened if you put dry ice in bleach?

What does the reaction that reveals invisible ink in citric acid

[@shivabadger]

The sugar caramelizes and burns, turning brown. Mixing up sugar water does the same thing.

[@andrewbenge4766]

Yeah, it's just breaking down at a lower temperature then the paper, so it can burn before it

[@-eMpTy-]

When you wrote your message using the lemon juice, carbon-based compounds in the juice were absorbed into the paper’s fibers. Also, since lemon juice ink is a weak acid, it softened the fibers in the paper. The added heat caused some of the chemical bonds to break down in the dried juice and some carbon was cut loose. When the carbon came into contact with air, it burned or oxidized. One effect of oxidation is things turn a darker color. (Some oxidation doesn’t need heat to occur; it just needs a little air. Think of a piece of apple, banana, or pear left out on a plate for a while.) Lemon juice - like most fruit juice - contains carbon compounds. These compounds are pretty much colorless at room temperature. Heat breaks down these compounds and releases the carbon. When carbon comes in contact with air (specifically oxygen), oxidation occurs and the substance turns light or dark brown. If it oxidizes long enough, it can go all the way to black.
