 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is fluorescent olive oil. What happens when I shine a green laser through olive oil? As always, adult supervision is required. What you need for this experiment is a green laser, olive oil, and some glasses. When you think of fluorescent, you think of garnish paper or clothing, but plenty of fluorescence can be found in nature. You can even start with your own kitchen, like with olive oil. You can even make it glow radioactive, like here, with this easy experiment. So with this experiment, I have two glasses. The one on the left is half water and half olive oil. And this glass right here is purely tap water. And you can see the green laser going through it is green. And then when I take the glass with half and half and I do the water on the bottom, once again it's green. But when I move it up to the top, it turns that red or orange color because of the fluorescence. Which I'll tell you a little bit later, the science behind this. So the science behind this, this process is called fluorescence. Olive oil contains a bunch of organic molecules that absorb light, one color and a minute to a different color. The glow seen here in the olive oil is fluorescence. The chloroform in the oil mostly reflects green light, which is why the oil and plants are green. But the laser light is so intense that electrons in the chloroform molecules absorb plenty of the energy anyway. The absorbed light raises the electrons to a higher energy level in these electrons that do all the work of the photosynthesis. In the oil, this chain is broken into electrons from the chloroform molecules to release the energy as a red light. So here I'm just shining the laser straight down on top of this tube where I've got a little bit of water on the bottom, which is the green, and then the olive oil on top. And what I'm doing is by when I shine the laser to the side of the glass, it reflects the light or the photosynthesis. And it'll actually curve and kind of gives a little bit of a light show, which is pretty cool. I hope you enjoyed this experiment.
