This cool LED Volcano Lamp allows you to get up close as it emulates the action of an erupting volcano with the motion beads and red LED lights, without running the risk of being engulfed by flowing molten lava! It's a great addition to any kid's bedroom or your workspace, and will keep you entertained for hours as you watch the lava beads float around. It looks fantastic in the dark, and can be switched off during the day! Not even Mt Vesuvius has a red LED back light... Simply fill with water and your lamp is ready to use! Note: If you are having any troubles getting your volcano beads to float about properly, remember to add just a few drops of liquid dish soap to the water as per the instructions. Requires 3 x AA batteries (not included). AC Power Adapter is optional but not included. Dimensions: 7.5cm (l) x 7.5cm (w) x 24.5cm (h).
