Water Marbles
Now you see them—now you don’t! The refractive index of water marbles is so close
to that of water that the marbles “disappear” when placed into water. The polyacrylamide
polymer spheres are stored dry, but after soaking for several hours, they will
absorb 200 times their weight in water. Instructions are included.
