Remember lava lamps? turns out, they’re like tiny universes. After the bulb’s heat distributes fully throughout the lamp’s interior fluids, spherical globules in various pastel colors and sizes begin to move slowly and silently about exactly as the natural laws of physics and fluid behavior require. Smaller globules coalesce into larger ones, then disassemble and separately join with others. Some globules at the base stretch languorously upward, merging with random spheres hovering at the top, and then both reform into a single, larger sphere, and then break apart and reform yet again. Some small globules independently slide around in the fluid, occasionally bumping into one another but bouncing off and traveling on independently.

The paragraph below describes how Cloudflare uses lava lamps to generate random numbers.
“Every time you log in to any website, you’re assigned a unique identification number. It should be random, because if hackers can predict the number, they’ll impersonate you. Computers, relying as they do on human-coded patterns, can’t generate true randomness—but nobody can predict the goopy mesmeric swirlings of oil, water, and wax. Cloudflare films the lamps 24/7 and uses the ever-changing arrangement of pixels to help create a superpowered cryptographic key. “Anything that the camera captures gets incorporated into the randomness,” says Nick Sullivan, the company’s head of cryptography, and that includes visitors milling about and light streaming through the windows. (Any change in heat subtly affects the undulations of those glistening globules.)”
