Yeeeee (camara flash) Joseph Are amazing Man Conner Coat. science was visiting the LA children museum and having my shadow captured on the wall so as a tribute to that moment i’m going to show you how to build your own shower wall and then we’re going to talk about the science behind what makes up actually glow and then we take it to the next level with the ridiculously talented artist buddy of mine but first i wanted to see if kids said that you think these four walls are as cool as I once did so we invited some family friends over for a party Chris you you when the dads came in the results were as expected you Oh Sears how you make it for projecting the light standard camera flash works great the higher the LA to the bed or you could sort of paint it with like UV flashlights or this blue laser a red laser doesn’t work Anna normal flashlight doesn’t work as well either and will there quiet a second for the wall I only were two options easy to use glow-in-the-dark paint or I found a place online that sells rules of glow-in-the-dark vinyl sheets you can put it directly on the wall ribosome half inch ear off just to make it pork and depending on how much is the wall you want to cover probably cost you somewhere between 50 it may be 200 bucks I put all the links in the description with even more details so I asked my super talented friend Jason balding to come over and see what he could do with the global but before we get to that let’s quickly thought about the science behind why sub close our eyes can actually see electromagnetic waves from 400 to 700 nanometers in length and our brain distinguishes them as colors so 400 is ooh and then up to 700 a meters is red as soon as a wavelength gets asked this band we can’t see it anymore and on the short-wavelength side we have ultraviolet or UV and on the longer wavelengths side we have infrared or IR they can keep going on the shorter wavelength side eventually you get things like x-rays you keep going on a long wavelength side eventually like Wi-Fi and even radio waves which could be the length of entire cities when you look at fluorescent colors something special is happening electrons and fluorescent materials get excited to a higher energy state by ultraviolet light that we can’t see and then when they return to their low energy state they have a visible light that we can see this is why they seem to glow in the Sun or under a blacklight invisible UV light comes in and then visible light comes out which is why they seem brighter more light is actually hitting your eyes that if they weren’t floor apt glow in the dark stuff is just a special case of fluorescence called phosphorescence the only difference is that instead of electrons can be excited and then releasing that energy right away phosphorescent materials have electrons that get excited but then we get trapped in this high energy state and it takes them a while I release the energy and get back to their original state and he’ll get back the same total light it’s just over a long period of time which is why they glow dip okay nowadays we also found that if you displayed an image with a projector you could burn that image into the wall and if you just let it on your phone you can sort of make a light stand a few months back I made a video about the scale of the solar system using just a drone and then just junk you find lying around your house for scale and you might have noticed that I didn’t include poor Pluto but I did include a new ninth planet that has been discovered with math that is ten times more massive than Earth and it’s super far away so the guy who was responsible for getting Pluto kicked out also happens to be the same dude who discovered this new ninth planet a few years later his name is Mike Brown and he is a Caltech astronomer and he also happens to be super brilliant and really funny he wrote a book called how I killed Pluto and Wyatt had it coming and it’s the best book I’ve read in the past three years and I power through two three books a month and I know a book about astronomy seems kind of lame but trust me on this it’s just one of those that changes the way you think about things and see the nice guy so the good folks inaudible who are kind enough to support this channel have made it so that if you want to listen to Mike’s book or any other book for free all you have to do is use the link of the description or go to slash mark Rover thanks for watching Oh that’s just yes Oh
