> Hmpf. You missed my point entirely, Joseph. For example, let's consider that air has an index of refraction of 1.002, and water is 1.333, and the Amazing Amoeba Man (theoretically) has a refractive index of 1.370 along his boundaries. So if you put Amoeba Man in water, he durn well becomes well-nigh *invisible* in that environment because the change in refractivity between himself and water is only 0.037. Compare that to the 0.368 between himself and air, which would render him *transparent* in air but not invisible.

You don't need science to become invisible. All you have to do is try to get waited on in a department store during your lunch hour.
