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®.
Heated deep within the Earth, the molten rock known as magma becomes lava when it erupts from a volcano or fissure in the planet's surface.The color of lava depends on its temperature and will change shades as it cools.
A Super Illusions Thinking Putty®, Super Lava shifts from bright orange to crimson copper. Then, dark brown to reddish black. Experience this amazing color shift for yourself!
