A laminar flow water jet system has a housing with a water channel, the housing creating a laminar flow in the water channel from the water flowing through the housing. A lighting element is provided with a controller. The laminar flow passes through at least one jetting element having a cup portion and a nozzle portion and jetting a laminar flow tube from the laminar flow passing through the water channel in the housing at the base portion. The laminar flow tube is ejected from the nozzle as a laminar flow jet having a smoothed tubular surface jacket and being lit by the lighting element. An additive source drips additive into the cup portion at a rate controlled by the controller, the additive being absorbed by capillary action by the laminar flow tube as it is passed through the nozzle to become the laminar flow jet. The absorption process drawing in air from the surrounding atmosphere and creating perturbations or bubbles within the laminar flow tube. In a further mode either an energetic pulse or an additive wave formed by increasing the volume of additive in the cup portion of the jetting element creates a wave perturbation or interruption throughout the laminar flow tube creating a variation in the laminar flow tube and the smoothed tubular surface jacket of the resulting laminar flow jet.
