Abstract
A fluid column projection apparatus and method provide a unique optical effect by providing a plurality of scoops that direct fluid into a hollow chamber. The fluid preferably contains one or more types of light-scattering material. The fluid exits the hollow chamber in a manner that projects the fluid to a considerable distance past the hollow chamber. The hollow chamber may be lit, or an external light source may illuminate the fluid, thereby providing a unique and pleasing optical effect in the form of a column of light.
