You are given the choice to live in the LIT room or the Musou Black room...what do you choose?

When he turned his flashlight on it looked like nuclear explosion footage.

Now do a Musou Black room with droplets of LIT splattered throughout it. Then it'll be like floating in outer space.

This is such a cool idea. Also: imagine a pitch-black maze covered with this pigment, but the only thing you have is a laserpointer. You can sketch out the walls using the laser finding your way to the exit.

It's amazing to see just how bright the paint is where it is thicker in some areas than others. I bet a second or third coat of the Lit would be phenomenal.

2:34 He's ripping the fabric of space

You should use the 100,000 Lumen Light in the black room too

The phosphorescence really highlights imperfections in the painting (like where the paint dripped it shows up as a bright pattern). Wonder if it would be more even if applied with a roller (or at least have regular variations instead of semi-random bright spots)?

so, during the day, or with regular light bulbs in a room, is it just like an ordinary white wall painted room? if so, this seems like a really neat idea for a children's play room

4:00 when you forget to turn on dark mode

“It feels very mystical and calming for some reason” Those are paint fumes my man

I like the feel that this running line on 7:45 is a living thing and lives it’s own life. Moves for some purpose

Just stumbled onto your channel. This is amazing! I was born in the late 50s. Back in the late 60s, there was a TV show called The 21st Century. They predicted that we would light our homes with light producing paint based on the idea that it would absorb sunlight during the day. Many of the predictions were way off. But it was a fun show to watch.

Can we all just appreciate all the work the action lab puts in his video’s? And like multiple times per week an upload!

James: it feels very mystical here and calming Also James the next second: Let's try to make a crime scene

I heard a story about a guy working on some road-related stuff "borrowing" some white paint from the workplace to paint his basement, but it turned out it was retroreflective paint used for markings in the roadway. From what I heard, the room had some interesting light conditions.

I wonder whether some sort of solution like this could be used in warm, developing countries as a way of powering lights without electricity?

Next up: The World’s Most Averagely Lit Room

This is what it would look like inside a Minecraft slime

I would've loved to have a room like this as a kid. Being able to draw on the glow-in-the-dark ceiling with a laser is a cool game/toy idea.

Im glad that you find answers to questions I never knew I wanted to be known

*Crash* “Oh theres my favorite corner.”

So that’s what it looks like inside a Minecraft slime.

I really love watching your vids, it is so helpful and mind blowing , even though some or most of your experiments can not be used in a normal living it will still make you think that "yeah, what if..." !

I love that harbor freight pneumatic paint shaker, everyone should have one

What I'd love to see? A Musou Black room, spattered with LIT to make stars.

The amount of effort and time you spend for 1 video must be mind blowing , Keep bringing good content for us , We sure do appreciate the work

Dude ALL your vids are so cool and fun. Thanks so much for all your hard work and ideas

The end bit with the laser and the music playing at that part made it feel like I was watching a little glowing spirit leave a trail of light as it danced around the walls of my room like in a ghibli movie or in the anime Mushi Shi

Everybody gangsta till they find a random handprint on the wall at 3AM.

4:53 its fun and games till you turn the light on and off ... see several human silhouettes on the walls ... but you are the only person inside the room.

How much pigment (lit) did you combine with a gallon of your white paint? I’m thinking of doing a project with this, any advise you could give would be greatly appreciated. Cheers. Really enjoying your videos!

I just stumbled upon your videos and man, thank you for doing this as well as your musou black video :)

“mirrors don’t reflect that much light, they only reflect 90-95% of light” Sounds a lot to me

Too cool! Really enjoyed the laser part.

I love and admire your curiosity!

Make it like a chessboard, black then white or like half black half white

Next: half the room with world's darkest paint, and the other half with the world's brightest.

My goodness!! That is the most glowiest thing I have ever seen! 🎨😮

woooooow AMAZING I love this ! tyvm ! 😍

I was literally thinking “I better see a frickin laser” about half way into this video... you did not disappoint

When he started tearing out the black paint I kinda died inside.

4:45 bogos binted finally met his end

The beat matching with the speed you placed the items at 2:46 was amazing editing,

Painting the floor with LIT and everything else with Musou would probably feel like you're on a floating platform.

So in the case of a power outage, I should paint my walls with LIT? Gotcha.

How about a room mixing all 3, the Lit, Musou and 'Ultra reflective' - i.e. bounce a few balls inside? (Following a kindergarten experiment with coloured bouncing balls)

This would be so nice in fl when you have hurricanes and the power goes out and it gets dark at 6pm and every room is 80° all the time 🙂

I could see painting a child’s actual room’s ceiling with this paint, and giving them a laser pointer to mess around with

POV: You can't pay for energy bills, so you paint your house with this.

Action Lab is so entertaining and cool. I never get so boring when watching these.

I'm thinking this paint would be excellent in areas like underground tunnels to help you get out if the lights go out. You'd only need a strip maybe near the floor of each wall. Of course, I also was imaging something like a racket ball court painted in Musou where the ball was painted in Lit... :-D

the black paint is so weird it sometimes looks like it is fake , like green screen :D

How to blind your enemy: Lock it into the room painted with the brightest white and turn on the most powerful flashlight you have inside.

LOVE GLOW IN THE DARK ANYTHING, NOW I WANT MY BEDROOM LIT

That's incredible.

Curious how it would look if you paint the floor with this and the walls with black

Plot twist: he painted the rest of his house Musou Black.

Musou Black with lines/strips of LIT. Strips of LIT around doorways, light-switches and other important markers, and the entire ceiling.

So calming

His grandma: IM SEEING THE LIGHT IM GOING TOWARD IT Him: no grandma you just walked into the wrong room

Fun experiment: put a bunch of people in the Musou Black room, hit one of them and leave. Ensured chaos

You are a genius! Please keep it up.

6:32 EFF YOU TOO, BUDDY! (Great video)

I can honestly say he looks like he was having fun.

When you are hungry in the night and open the fridge for a midnight snack.

I thought glow in the dark things could maybe be charged with warmth! I wash this glow in the dark Keychain and I could've sworn it got brighter

As a construction worker, specifically an electrician, this video was quite exciting. I am currently working at a jobsite that is a remodel, plus new addition. Everything got killed during the demo phase before remodel, there is no power or water to the remodel portion. Due to weird problems specific to this job, getting temporary power is probably 2 months away. What kind of temperatures are realistic for getting at least a dim lighting effect for an hour or two? Or is it mere minutes? We are accustomed to starting at 6 am so we can get off at 2:30 pm, but because of the circumstances of this job, we have to start later when we can see, and use portable battery operated lights and headlamps for at least an hour in the morning before we can see with ambient light. Summer temperatures are in the high 80s to mid 90s in my locale, is that enough to 'charge' this paint, and how expensive is it? Standard commercial building light fixtures are 2' x 4', my mind is picturing painting a few pieces of plywood (after a bit of thought, perhaps pieces of sheet metal would work better) that size in this paint and using them as 'lights' of a sort, after charging them by putting them next to a blowdryer or the like run off a generator. Am I dreaming, or is this a viable possibility? If I got the video right, truck headlights could even charge such "lightboards", as both light and heat work.

No one: People’s teeth in any toothpaste commercial:

Imagine that room with a discoball. the streaks of light left behind from the reflections would look mesmerizing.

It seems like this could be super useful in places where electricity is scarce and really in any place that electricity could go out (every home/business basically) I mean sure you might think glowing green walls are a bit obnoxious but you could paint strips of it around the bases of floor and around doors if you wanted some a more subtle but still useful 'lighting'

@3:57 Bert Simpsons "Am nervous" 😂😂😂🤣🤣 Priceless.. Thank you #TheactionLab

Now I wanna paint a room with Musou black and use LIT to paint stars and constellations...

For anyone wondering, the LIT pigment is made by Stuart Semple; best known for his blackest black, the pinkest pink, and his beef with Anish Kapoor.

very cool. seems like there could be some cool applications for something like this

Isn't this the future of sustainable lighting? There's gotta be something more to this than paint... Incredible!

"Whitest thing in the world" Clearly you haven't seen me try to rap

Now next Video: Schrödingers's Room *Musou black and lit room* at the same time

This is every single child's favorite room. They can just draw everywhere.

I'd be curious to see the results if you had tested it out with a UV/blacklight.

"Look how bright" Camera's auto ISO "ehm, well..."

Action Lab: "Hey, do you like your eyes?" Me: "Yes." Action Lab: "Me neither!"

I would've been curious to see a timelapse of how long does it takes to stop glowing versus how long you charge the paint with the light.

Great info and presentation

“Painting world’s brightest room” Next video: “How I went blind”

imagine being a kid and your parents own the world darkest room. Parent: That's it jimmy, into the void room you go, 30 minutes. jimmy: please, i don't wanna experience the void

I feel like they should use this for watch hands. Lume is a constant problem with watches, but this would likely keep the hands glowing just from your body heat, or, if too cold for that, it still would be great lume paint.

2:05 ~ I've been wondering about that hand increase in glow for years. I thought it was a reflection of the glow, back to the glow off the hand. So it's the heat that does that. ;)

I'd imagine the black you just tore off cost more than the walls you tore it off of.

"world brightest room" *man turns green*

This reminded me of Del Boy and Rodney using industrial painting for kitchen

Its really cool and fascinating

Here's the dream: a ceiling painted with LIT and the walls painted with musou black.

imagine if this paint existed before light bulb was invented

Try to do an experiment with the Musou Black room and move like there's no gravity, you'll really feel what space is like!

This is honestly so cool, who knew the world's brightest color can literally shine without light

imagine if a burglar broke into the garage and saw this... the dudes gonna be traumatized XD

“There’s my favourite corner” I feel this

THIS IS SO LIT PAINT ROOM YESSSSSS!!! SLAYYYYYY

Now make a half black half white room and... *MEMENTO MORI UNUS ANNUS*
