Super Illusions Super Oil Slick Thinking Putty by Crazy Aaron has colours that shift and morph right before your eyes.

You'll be hypnotized by the mind-boggling liquid metal appearance with green and gold alongside hints of silver and blue.

Everyone knows that oil and water do not mix. Yet when they do, what is known as an oil slick appears. An oil slick creates a colourful layer of oil that floats on the surface of water. This layer is highly reflective due to the light wave interference between oil, air, and water.

This undulating refractive index makes for shifting colours that move and change with light. You will see the same effect in Super Oil Slick—an extremely popular Thinking Putty colour that is downright mesmerising.

Crazy Aaron's Thinking Putty is a fun silicone-based putty that is non-toxic and is perfect for busy fingers.

It can be used to foster creativity, conduct scientific experiments and provide fidget relief for children, and stress relief for adults!
