See the Groovy Process Behind How a Lava Lamp Gets Made
Making a lava lamp isn't quite as trippy as watching one, but it's still fascinating. The process involves mechanical glass blowers, liquid wax, top secret ingredients (a mixture of chemicals and dye), and 160°F baths. The psychedelic liquid inside the bottle is made of wax and the aforementioned chemical mixture, and expansions and contractions in response to changes in temperature are what make the colorful gloop travel up and down the bottle. Watch how it all gets put together in the video above from Science Channel.
