Transport the wonder of the Northern Lights into your living room with the Liquid Laser. This small globe creates an infinite number of hypnotic patterns which dance across your walls & ceilings using high quality laser technology. The Liquid Laser comes with a variety of functions so you can change the effects according to your mood. The laser patterns are clearly defined & the speed they appear can be adjusted. There are six different effects using a combination of the red and/or green lasers plus the special effects lens. Simply switch on & you can control the speed, whether to have just the red or green lasers or a combination of both & the choice of adding the special effects lens which diffuses the pattern over a wider area. The Liquid Laser is either battery (3 x AA) or mains operated. Before switching on, ensure the laser is pointed away from you at all times as the class 2 laser can cause permanent injury if you stare into it. The direction of the Liquid Laser can be adjusted. Height is 17 cm.
