It is based on very basic scientific principles and contains only a few simple components. Necessary components of lava lamp: compounds that can form floating "bubble blocks", compounds that can make bubble blocks float in them, and light bulbs, which are used for lighting effect and provide heat needed for bubble blocks to move.
In order to make floating bubbles, the two compounds in the lava lamp must be immiscible, that is, immiscible with each other. This means that liquid A cannot be dissolved in liquid B, and the two cannot be mixed, so you see two separate liquids, one floating on or in the other.
The design of lava lamp is inspired by the egg hour hand, because it uses the principle of heat energy to create the eternal effect of light and shadow movement and change; The appearance is extremely cool, but the low technology is extremely psychedelic, and now it has become a popular relic.
Nowadays, lava lamps have developed into a variety of colors, shapes and sizes, becoming an eternal fashion, the first choice for gifts and home decoration, and also an essential ornament for college students' dormitories and offices. And because of its slow change, endless effects will make people daydream.
history
1963, British entrepreneur Edward craven walker (? Edward Craven Walker came up with the idea of lava lamp after seeing a homemade egg cooker, which is made of cocktail mixers filled with liquid and bubbles on the stove in a bar. He hired the British inventor David george smith to develop the equipment and its chemical formula.
Smith is regarded as the inventor of the original American patent 3,387,396 "Display Device" filed in 1965 and assigned to Craven-Walker Company, which was subsequently published in 1968. ?
Craven Walker's company, Crestworth, is located in Poole, Dorset, England. He named the lamp "Astro", and there were variations such as "Astro Mini" and "Astro".
1965, Adolph Wertheimer and Hy Spector became interested in Walker's products when they saw them at the German trade show. They bought American rights and set up a lava manufacturing company in Chicago to sell what they called lava lamps.
In the late1970s, the rights of the United States were sold to Larry Hagarty, who set up a subsidiary of his company, Hagarty Enterprises, called Lava World International, which has been producing American lava lamps for more than 30 years.
In 2003, Lava World International (formerly Lava-simple-scribe International), an American manufacturer of lava lamps, transferred its production to China.
In 2008, it was acquired by Talon Merchant Capital and renamed Lava Lite LLC. As of 20 16, lava lamps are sold under the brand of Lifetime in North America. ?
In 20 18, the brand "Lava Lamp" was acquired by Schylling Inc, a toy and gift manufacturer located in North Andover, Massachusetts. Who continues to hold the American trademark rights of the shape and name of the lava lamp.
After selling the American copyright, craven Walker kept the copyright in other parts of the world and took over two business partners, Cressida Granger and David Mully, in the late 1980s.
They finally took over the company and changed its name to Mathmos on 1992. Edward? Craven Walker served as their consultant until his death in 2000.
Mathmos continues to produce lava lamps and related products. They won two Queen's Export Awards and the Best Multimedia Award in Design Week. ?
Astro lava lamp was launched in 1963 and celebrated its 50th anniversary in 20 13. ? Mathmos lava lamps are still produced in the original factory in Poole, Dorset.
