 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the glow-in-the-dark laser pointers. As always, adult supervision is required. Remember, avoid direct eye contact with lasers. What you need for this experiment is glow-in-the-dark paint, which I got mine at the local craft store. And I'll show you the description where I got mine and what kind it is. I also have just a regular white flashlight that I pulled out of the closet. And then I also had three different laser pointers I got on Amazon. I got a red, I got a green, and then I also have, at the end, I've got a violet one. So, turn the lights down a little bit using the green laser. And I've painted that white piece of paper there with the glow-in-the-dark paint. And what you can't see is that when you turn the laser off, it does have a light glow, and it is reflecting a little bit. So I turn the lights off all the way with the red one, and I'm unable the same thing happened. I could not see the glow on the camera, but there was a glow. So with the violet one, you can see how well it works. You just kind of go around and draw any kind of line you want, and it just shows up very well with the violet one. So glow-in-the-dark paint is made up for special molecules called phosphorous. To move at a higher energy level, they need energy from photons. When the photons from a light source hit the molecules, they excite the electrons. The energy of the photon is based on the wavelengths. So if you think of a rainbow, red has least energy, and the violet has the most energy. So that was why it was so hard when we couldn't see the red, because it has the least amount of energy, where the violet, where it really shows up, is because it has the most energy. Due to the wave particles of light, you have to have a wavelength of light that is shorter than the wavelength of the light or the glow-in-the-dark that is emitting. So that's why blue violet works so well. So here we go with a regular flashlight, and it's just white light, and surprisingly it works. And that's because, you know, white light has all colors of the rainbow. So therefore it does have a lot of violet in there, and it's going to be able to work, which is pretty impressive. So here I have a strip that's just made of those, you know, those like those stars you put on your ceiling, the glow-in-the-dark, this is just a long strip of it. And when you take the violet laser pointer and you put it onto one of these glow-in-the-dark strips, or like a star, it actually really holds the light very well. It's pretty impressive. So I will try to be a little artistic here or spell it out by putting a little kids fun science here. And you can see it really taking that violet laser pointer really just highlights and really soaks in that energy into that glow stick or that glow bar, which is pretty impressive. Even when you turn the lights on, you can see it really holds that energy inside there, and it will stay in there for a long time, which is pretty cool. I hope you enjoyed this video.
