  • Phantom Crystals are carbon-based polymers that absorb up to 300 times their weight in water. A fully saturated crystal in a glass of water is almost invisible, as light passes through it without being refracted. But when exposed to air, the water soaked crystals are clearly visible, because air’s index of refraction is very different from that of water.
