Novelty bubble lamp with silver base. The colour changing LED lights illuminate and send a variable steady stream of bubbles up the tube, which in turn creates oscillation and the fish appear to 'swim' up and down. Makes a great feature in homes, schools, sensory rooms and workplaces. It is important that this product is placed on a level surface and where it will not be knocked over. To keep the lamp clean, use mild soap and water do not use any abrasives. Only clean and distilled water should be used for cleaning as other types will affect the function of the product and may cause algae growth. Plastic multi-coloured artificial fish are supplied.
