 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the microwave light bulb. As always, adult supervision is required. What you need for this experiment is a light bulb, glass, and a microwave. Safety precautions. Perform this only under adult supervision. Do not perform this experiment longer than 15 seconds and wear safety goggles. As long as you follow the safety precautions, everything should be fine. The setup is really easy. You get a glass of water and fill it about halfway full and then you put your light bulb in the glass and then you're going to put that in the center of the microwave right there and then you're going to set it for no longer than 15 seconds. So I set it for 15 seconds and you're going to turn it on and you're going to see as it starts to spin that it's going to light up. Pretty cool. It's pretty awesome. You can do this over again. Be careful. The light bulb will be hot when it comes out and then I will tell you the science behind this. Alright, so the science behind this, the light bulb will light up when the microwave is turned on and this is possible because the tungsten filament within the light bulb is able to absorb the microwave radiation. As the filament absorbs energy, it becomes so hot that it glows. Fulfillment within the incandescent light bulb doesn't actually burn, but it rather glows like that as it becomes hot. The bulb is submerged in water so it can prevent the microwave from striking the metallic base of the bulb and reflecting off, causing damage to the microwave. So it's completely safe as long as it's in the water holding that metallic part out of the range of the waves. I hope you enjoyed this video. Remember to click thumbs up and to subscribe.
