Lava lamps are often filled with wax, water, and other chemicals to make them look brighter and colorful. The lava lamp experiment measures density and polarity.Īns: Yes. The real lava lamps use polar and nonpolar liquids, just like the homemade ones do. The water and gas combination is less dense than oil, and hence they rise to the top of the flask. What Chemical Reactions Take Place in The Lava Lamp Experiment?Īns: The Alka seltzer, when reacted with water, produces carbon dioxide gas bubbles. You can keep your lava lamp actively working by adding more tablets from time to time. The bubbles disaster as soon as the reaction stops. As soon as we add the fizz tablets, small bubbles appear that come to the top and bring some water along with it. Although the water and oil layers separate due to the densities the food couriering has the same density as that of water. We observe that in the lava lamp experiment, the density of oil is much lower than that of water. In case the lava lamp reaction stops, keep adding more tablets. The reactions will start inside the bottle as soon as the tablets are added. Start adding them to the flask one by one. Take an Alka-Seltzer tablet and break it into small pieces. Since the food coloring is also water-based, it will sink and settle at the bottom of the flask. Let the vegetable oil and water levels separate.Īdd food coloring to the mixture. Now add vegetable oil to the bottle until it is full to the brim. It is advised to use a funnel so that the water doesn’t spill outside. Let us see how to make a lava lamp.Īpparatus Needed For Lava Lamp Experiment:įill the bottle or flask with water. The lava lamp experiment works on the principle of density and polarity. You can change the batteries too in case the lamps stop working. A lava lamp usually starts working an hour after turning them on. After this, you can either replace it with a new lava lamp or bring a new bottle. All of this happens in very slow motion, and the density changes that occur are very mild.Ī bottle of a lava lamp is said to last nearly 2000 hours. As both the liquids have similar densities, the previously denser liquid becomes lighter and rises over the other liquid. While expanding it low becomes less dense. The denser liquid will absorb the heat and expand. Once you have found the two liquids, heat the bottom of the mixture with a light bulb. So you need to find two liquids with very close densities for the experiment to work. But the two liquids have densities that are very different from one another. Many people often end up using oil and water because they are insoluble in each other. In the lava lamp, we have liquids that are very close to each other in density and are insoluble in each other. The lava lamp science project hypothesis talks about the density of two liquids and the solubility of the two same liquids. I always seem to learn something new from GameDev members.Lava lamps, also known as liquid motion lamps, have been doing the rounds for ages. That's some quick brainstorming, but something leads me to believe that there is a much better way to simulate this.Īny thoughts? Feedback much appreciated. Then I'd have to use some pretty hefty collision detection, and test for the proper animation frame to be displayed, based on the variables of the collision. I was thinking that I'd start (and this kind of a stab in the dark) with some 3D models of blobs, that I'd create with truespace and create some animation states for one blob. What I wanted to get some feedback on some possible approaches to creating the effect seen in lava lamps. I'm already very fluent in C/C++, OpenGL, and DirectX, so we're way past that part. The thing is, I'm not really sure how to approach this 'liquid physics' type simulation. I was watching my girlfriends lava lamp the other day, and thought "that would make a really cool screen saver".
