 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is baking soda and vinegar lava lamp. Hi, welcome back to Kids Fun Science. Today I've got a really easy experiment. It is similar to the lava lamp that uses the oil, water, and food coloring in an aqua seltzer tablet. This is much cheaper and I actually found it from one of the people I follow on Instagram from Russia. And so she helped me. She's very generous and I got her information here and I also have it in the description. You got to check out her channel. But she used tea soda, which is compared to our baking soda here in the United States, which is just basically a sodium bicarbonate, right? So you could use that. You need the vegetable oil. You need a vinegar. Now she suggests using 9% vinegar and I'm going to try 5% vinegar because that's what I have. And then a glass to be able to put it in, optional food coloring, and some teaspoons, right? So to be able to dump it in. So what I'm going to do is set it up and then show you how the experiment works and then a couple different ways I've not played with it. What's great about this is she's right. It is a lot cheaper. I already have the vinegar and the oil and everything else. So it was a lot cheaper where the lava lamps, you have to go buy the Alka Salsa tablets, which are quite expensive at some point. So I hope you enjoy. So you take a large glass or a large vase like I have and you're going to fill it up with vegetable oil about three quarters of the way full. Then you're going to take your baking soda, which is your bicarbonated soda, and you're going to put three or four scoops in and you'll see the baking soda will go all the way to the bottom of the glass. So I took red food coloring, put it in my white vinegar, which is about 5%. And now we're going to start the experiment where we're going to scoop in about three to six scoops of the vinegar into the oil. Now you get to sit back and watch the chemical reaction. So the science behind this is oil is less dense than baking soda and vinegar. And that's why those two sing to the bottom. When the vinegar and acid and a baking soda, a bicarbonated soda, a base, they mix, they make a chemical reaction. One that we produce when we breathe out the same gas, a carbon dioxide. So those gas bubbles are what we're seeing come up when the vinegar and baking soda combine together. They make that gas and the gas bubbles go all the way to the top and then they release back down and the process continues. As it starts to slow down, the great thing about this is you could just start adding more vinegar to it and it will kick up the reaction and continue to do the same process over and over. So this time I started off with the blue vinegar and then I started adding some red to get that multiple effect going so you have a couple different colors, which I thought was pretty cool. You probably can do a whole bunch of different ones, but as it started to slow down, I just added some more of the blue and it continued to go. I hope you enjoyed this experiment.
