From time to time a rotating sprinkler will create a fleeting rainbow due to a combination of drop patterns and sunlight. Rainbow Irrigation System recreates this spectacle on demand for your enjoyment as the water circles around your lawn or field. Here's how it works:
At the base of the sprinkler an additional item of apparatus is attached that delivers a fan array of laser light, the effect of which has been precisely calculated to create consistent r.o.y.g.b.i.v. spectrum of colours within the water being sprayed. This is like having a rainbow orbiting your garden.

It's the perfect way to relax on a nice sunny day, but in a dark evening it's even more spectacular, with multiple sprinklers being capable of creating a complete light show at the same time as they irrigate a large area such as a public space.

Rainbow generation system - sounds like the first steps in a leprechaun capture system.
