 Welcome back to Kids Fun Science. My name is Ken and today's experiment is the homemade lava lamp. As always, adult supervision is required. What you need for this experiment is the alcocellular, a bottle, water, food coloring, and veggie oil. Safety precautions. Do not put the cap back on the bottle while the alcocellular tablet is still bubbling. To start off, you fill a bottle which we have a one liter, about a fourth of the way full of water. Then you're going to take a funnel of any sort and you're going to fill another two-thirds of the bottle with vegetable oil. I just use a generic brand that I got at Walmart. So you put your funnel in and start pouring in an angle your vegetable oil so it doesn't so it lays right on top of the water as you can see here and continue to fill until it's about about an inch or so from the top. Now you're going to take the color of your choice for the food coloring. We chose blue and you're going to put in about eight drops of food coloring. That just really depends what color, how dark you want the water on the bottom. As you see, the food coloring is going to, it's lighter than the vegetable oil, so it's going to sink down to that bottom layer for now. Now we're ready for the fun part. We're going to put in an alcocellular. Though I've never used it personally, I do buy a lot of it for science experiments. We're going to put a whole tablet in, but since it's a one liter bottle, we're not going to be able to fit it in. So break it in half and put it in. It's going to start making bubbles of carbon dioxide. That's going to spread the color in. Now you see the blue and then it's going to grab water droplets with some air on it which brings the air and the water droplets up to the top and when the air pops, the water will sink back down to through the oil to the water again, hence making your lava lamp. So this will continue to go until the alcocellular is completely done and then all you have to do is break out another alcocellular tablet and redo it again. Always remember to keep the cap off the bottle while you're doing the experiment, but after it's completely dissolved, you can put the cap back on and store it and for another time when you decide to use alcocellular.
