Cloaking Spray

Man has been fascinated with invisibility since ancient times

In Greek mythology, Perseus used a cloak of invisibility to slay the Gorgon Medusa. Back in the era of alchemists before modern science, the quest for invisibility was almost as important as the formula to trans-mutate lead into gold.

Let's just propose for a moment that the information in the video below is true. That fictional characters are describing a real project...currently in development. The industrious (fictional) engineers at the University of Michigan have moved one step closer to achieving that goal. They developed a cloaking spray that once dry, renders any object its sprayed upon almost invisible to the naked eye. Light moves in the size of Nanometres. Once engineers began working on the Nanoparticle scale they could directly interact with light.

These engineers have created a cloaking spray composed of a liquid Nanoparticle solution that bends light. There have been several inventions that bend light to give the illusion of invisibility. Yet none have achieved the level of success as the engineers in Michigan. Their cloaking spray is unique in it's versatility. It can be sprayed, coated, or painted on any surface and make that object... disappear.

This may be science fiction, but it describes advanced nanotechnology...and it's awesome. Curved objects like spheres and bottles work better than straight edged forms, like squares or triangles. When shapes with straight edges are coated with the cloaking spray the edges are visible when it drys. Although this is a minor setback, the team have already successfully coated gloves, clothing, fruit and numerous other objects and materials with success.

The military is funding the project (of course) so they have funding to overcome any problems that may arise. Plans for invisible drones, and reconnaissance vehicles are already on the way. The engineers hope to begin human testing in the next few years. The whole idea makes me think of the movie Hollow Man...imagine that. 

For more information on the cloaking spray (prank...or project in development) and the science behind it, check out the video below
