re: amazing
Actually, they are not making the substance invisible...only transparent. The ordinary liquid crystal displays in wristwatches and other gadgets already do that.
However, I can envision a process that would allow us to immediately render a object not only transparent, but actually completely invisible. To do this, the object would, after becoming invisible, have to have a density equal to that of the surrounding atmosphere. The process would involve the manipulation of the electrical forces inside of an atom in such a way as to alter the electronic structure of the atom and make it incapable of interacting with photons of visible light.

On 7/6/06, I found, in any overbalanced gravity wheel with rotation rate, ω, axle to CG distance d, and CG dip angle φ, the average vertical velocity of its drive weights is downward and given by:
Vaver = -2(√2)πdωcosφ
Vaver = -2(√2)πdωcosφ
