Create a colorful and fun atmosphere in your home with this LED 5-Piece Oval Jellyfish Lamp Set with Black Base. It is sure to turn heads and brighten up any room in your home. It features a variety of color-changing modes that are perfect for mood lighting. Simply fill the tank with water (approx. 2 liters), sink the jellyfish into the bottom of the tank, flip the switch and watch the jellyfish float to the surface, creating a mesmerizing underwater scene. The jellyfish's tendrils even float behind the jellyfish as it moves, creating a realistic effect. This soothing ambient lighting creates a stimulating and calming environment for children and adults alike, while providing a captivating visual point of view. Place the jellyfish upside down in the tank. If the jellyfish supplied with the light does not float properly, check for small air bubbles on it and add 10 drops of dishwashing liquid to the water. Gently tap the jellyfish to disperse trapped air bubbles, this will help the jellyfish to remain properly buoyant. If necessary, use a stick to disperse air bubbles. Then, reseal the aquarium with a rubber stopper and plastic lid.
