The mixture looks like liquid but when touched again feels like a solid.

Non Newtonian liquid is a special compound with a viscosity that does not conform to Isaac Newton's internal law of friction. One way to make non-Newton liquid is to mix corn flour with water, according to Seeker.

The mixture looks like liquid but when touched again feels like a solid. This property comes from very large liquid particles. When abruptly exerted like punching on the surface, they do not have enough time to move like normal liquid and solidification. If they stop the force, they become the same liquid again.
