It looks like an ordinary glass of water... crystal clear water. But hiding just below the surface of the water is an amazing collection of large, jelly-like marbles that become invisible when submerged in water. The Jelly Marbles become invisible due to an identical index of refraction with the liquid. In other words, they vanish like magic! As you'll see, there's more to this experiment than meets the eye.
