Crazy Aaron’s Illusions Thinking Putty can be stretched, sculpted, bounced, and shifts its colour right before your eyes. The illusion is a result of thin-film interference, a process caused by light waves that are reflected and refracted by the putty’s structurally complex coating. Produced when geothermal energy heats rock deep within the Earth, lava is a fantastic example of this colour shifting phenomenon. The colour of lava depends on its temperature and it shifts its shade as it cools from orange, to crimson copper, to brownish red, to black. About Thinking Putty Thinking Putty is a silicone-based putty that never dries out. Nontoxic and safe to use, it can be stretched, kneaded, twisted and moulded to relieve stress throughout the day.
