Here is one of my favourite examples of "Outside the box" Thinking.
How would you describe a bullet-proof vest ? Hard, heavy, stiff and bulky ...
Dr. Norman Wagner, a professor of chemical engineering at the University of Dela-ware's Center for Composite Materials, has a different view. Initially, Wagner and his team envisioned armor that could be spread on a person, almost like peanut butter on bread. And they were able to developed a liquid material to turn soft, flexible fabric into a tough, stab-proof, bullet-proof material.
The material is a mix of liquid polymers and silica (tiny sandlike particles). Together they produce a "sheer-thickening liquid" that stiffens instantly into a shield when hit hard by an object. It reverts to its liquid state just as fast when the energy from the projectile dissipates.
Sounds like Sci-Fi ? Check it out =)
