Yeeeee( camara twinkle) Joseph Are amazing Man Conner Coat. science was seeing the LA children museum and having my pall captivated 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 concludes up actually glow and then we take it to the next level with the ridiculously talented craftsman chum 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 lineage very good friends for a party Chris you you when the fathers came in the results were as expected you Oh Sears how you make it for projecting the sun rule camera flash uses huge the highest the LA to the bunked or you could sort of paint it with like UV flashlights or this blue laser a crimson laser doesn’t work Anna ordinary flashlight doesn’t work as well either and will there placid a second for the wall I exclusively were two alternatives easy to use glowinthedark paint or I acquired a place online that sells rules of glowinthedark vinyl expanses you can employed it instantly on the wall ribosome half inch hearing off simply to make it pork and vary how much is the wall you want to cover probably cost you somewhere between 50 it may be 200 horses I put all the links in the description with even more details so I expected my super talented friend Jason balding to come over and experience what he could do with the world but before we got to get 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 span and our brain recognises them as colors so 400 is ooh and then up to 700 a rhythms is red as soon as a wavelength gets asked this band we can’t see it anymore and on the shortwavelength side we have ultraviolet or UV and on the longer wavelengths place we have infrared or IR they can keep going on the shorter wavelength line-up eventually you get things like xrays you keep going on a long wavelength side eventually like WiFi and even radio wave which could be the length of entire metropolitans when you look at fluorescent emblazons something special is happening electrons and fluorescent textiles get excited to a higher energy state by ultraviolet radiation that we can’t see and then when they return to their low-pitched exertion country 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-headed is actually hitting your eyes that if they weren’t floor apt radiance 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 vigor right away phosphorescent information have electrons that get excited but then we get trapped in this high energy state and it makes them a while I liberate the vigor and get back to their original nation 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 too found that if you displayed an portrait with a projector you could burn that portrait into the wall and if you is letting it on your telephone you can sort of make a light-headed stand a few months back I made a video about the scale of the solar system use just a hum and then time waste 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 brand-new one-ninth planet that has been discovered with math that is ten times more massive than Earth and it’s super far away so the chap 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 mention is Mike Brown and he is a Caltech astronomer and he likewise 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 notebook I’ve predict in the past three years and I capability through two three volumes a month and I know a book about astronomy seems various kinds of lame but cartel me on this it’s just one of those that changes the nature you think about things and ensure the nice guy so the good kinfolks inaudible who are category enough to support this channel have attained 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 specific characteristics or go to slash mark Rover thanks for watching Oh that’s just yes Oh
