What do an oil slick, a lava pit, and insect anatomy have in common? It’s something called thin-film interference, which is caused by light waves that are reflected and refracted by a veiled or structurally complex coating. Often called iridescence, this phenomenon causes all of these things to shift colors right before your eyes. It’s also the secret behind our amazing Super Illusions Thinking Putty.
When geothermal energy heats rock deep within the Earth, the molten result is called lava. Lava takes many forms, but the most well known erupts from a volcano or fissure in the surface of a planet.
The color of lava depends on its temperature and will shift shades as it cools. Bright orange gives way to crimson copper. A dark, brownish red fades to black as the lava shifts from a liquid to solid. Experience this amazing color shift for yourself with Super Lava Thinking Putty.
Each tin includes 1/5 lb of Super Lava Thinking Putty—a huge handful for tons of fun.
