Edward Craven Walker created the lava lamp in England in 1963. Adolph Wertheimer and Hy Spector , two entrepreneurs from Chicago, discovered the creation at aGerman trade show in 1965, according to eHow , a popular website. Wertheimer and Spector were so fascinated with the creation that they purchased therights so that they could sell the lamp in the United States. The invention originally was called the Astro lamp, but after the two entrepreneurs acquired the patent for thelamp, it was renamed lava. Recently, participants in Fun with Physics Friday decided to tryremaking the 1960s invention. Fun with Physics Friday first came about in 2005, astronomyProfessor Alfred Alaniz said Oct. 5. Alaniz created activities where students could dismantle and reassembleitems. Students disassembled items at their home that they were notsupposed to and their parents became frustrated with them, he said. So he told students to bring old appliances in an attempt to repairthem, and if they could not be repaired, materials would bescavenged for future projects. This is how Fun with Physics Friday was created, Alaniz said. Alaniz said throughout the week students come up with ideas and onFriday follow through with them. The Sept. 28 project was trying to construct lava lamps. The materials consisted of a burner, mineral oil, food coloring,deionized water, rubbing alcohol, thermometer, beaker, graduatedcylinder, turpentine, and oil-based paint, biochemistry sophomoreSergio Loera said. A week later, on Oct. 5, the students finally concocted a workingformula for the lamp. The formula is: First, mix paint with mineral oil, and then measure density. Next, mix alcohol and deionized water and measure density. The density of both have to be as close as possible, but themineral oil has to have the higher density. Finally, combine all the ingredients, then heat with a burner. The students attempted to create the lava lamp 12 times beforesuccess. Loera said a good quote he stands by is, In order to have a greatidea, you must first have a lot of ideas.
