 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the holiday spec holographic lenses. As always, adult supervision is required. What you need for this experiment is holiday spec glasses. I picked mine up at the local Christmas store, but I'll show you in the description where you can find those online and order them yourself if you desire. Here's what they look like. They're made out of paper. They're very cheap around a buck fifty and look in the description where you can get them. When you look up close through these diffraction glasses, you're looking through a piece of material called the diffraction gradient. This gradient is a piece of plastic that has small openings, which usually is narrowed through the closing space of each other. When light passes through these openings, it bends in the amount of the dependent of the type of light. For example, red light bends more than yellow light. When the white light enters the diffraction gradient, it separates into a fundamental color. These colors are the same as the spectrum of the colors that you see in a rainbow. Here you can see I put on the glasses and you can see it turns into candy cans. You pull them down and you've got your white, red, and green Christmas lights. I'm sure you still have them around. So we also have different glasses. So we have here we go. We pull it up. We got the Santa's face and you pull them down and it's kind of cool. It's doing every individual light on the glass because of the way it's set up on the lens that each turns into that image. And here's a snowflake. So basically the science behind it is the as I showed you earlier, the micro etchings into the plastic lenses causes the light to diffract the shape that is etched onto these glasses. Hence like this one is a snowman, right? So understanding how it works isn't easy. It's an interesting property of nature of light that's going through these glasses and diffracts, in turn transforms that image. One thing is it doesn't matter where the light moves through the glasses. The glasses will always show you the image that you have no matter how many lights are out there. It will refract that many, which is pretty cool. I hope you enjoyed this video. Remember to click share or like and thanks for watching.
