A Global Gizmos Retro Tie Dye Lava Lamp 16 inch is a fun way to add a touch of colour to a room, perfect for giving any room in your house a retro feel. The lamps give off a calming atmosphere and will help give you relax as you watch the coloured bubbles float up and down. They come in an array of different colours and styles so you can pick the best one for your home. Please be aware that the lamps do get quite hot so to keep them out of reach of children. The mains operated lamps come with a bulb which provides the warming glow within the tube. Watch the different-sized formations of melted wax collide, flow, and split apart as they ooze their way up and down the glass globe.
