Check out this extremly satisfying video, of a guy playing with Kinetic sand. The Kinetic sand acts like liquid, yet it doesn’t stick to anything, but itself. It’s made of 98% sand and 2% polydimethylsiloxane which is a type of silicone oil , that mimics the physical properties of wet sand. It was originaly designed for sculpting.
I think we need a 10 hour video of this! 😀
