The exact materials used are a proprietary secret, and no one knows what they are. You can easily see that the key to making a lava lamp is to select the right fluids. Then, it heats back up again, and the process is repeated over and over until the light is turned off. The heat from the bulb warms that dense liquid on the bottom, making it hotter, which then makes it rise to the top.Īs soon as it reaches the top part, it cools off and then floats down to the bottom. This heated fluid can rise and sink faster, which makes the “lava” move up and down in the glass. Sometimes, they’re chosen because of their expansion properties, as well. They’re selected based on their density, as one has to float when mixed in with the other. The “lava” effect you see in these lamps happens because of the interaction between the two fluids used. By 1990, more than seven million units of these lamps were sold. Most people thought the fad would die down, but it never did. With the addition of pop art and psychedelic products that came out around the same time, the gimmicky light was a major success. Once created, they changed the name to Lava Lite Lamp. They bought the rights so that they could manufacture the lamp in the United States. So, Walker took it to a German trade show in 1965, where two American inventors saw it. Walker then worked hard to build the original version of the lava lamp, which he called Astro Lite. He requested to buy the prototype from the owner and focused on making his own. The early version was made using a cocktail shaker and a variety of other things. He was a British engineer who saw a prototype in a pub. Who Created It?Ĭraven Walker has always received credit for creating the lava lamp. The psychedelic effect of these lamps has always been fun to watch.

The oily substance inside rises and falls within the lamp, changing its shape, breaking up, and then forming again. These lamps come in many shapes, sizes, and colors and are designed to look like molten lava, which is how they got their name. One look at it and you’ll know that there are two materials inside: the liquid and something else.

They generally contain oily, colored fluid that moves up and down in a seemingly empty structure. Lava lamps are designed to be decorative light fixtures in the shape of a tube.
