Our amazing 9.5" White Color Changing Rainbow Orbs have many settings to choose from. You can set it to change colors, or set it on one color: Red, Green, Blue, or White! These FLOAT and are waterproof, so they look great in a pool or other water feature. On the bottom is a recessed loop to attach a line for hanging it or to anchor it for your floating applications. The waterproof floating orbs are meant to float on top of the water, not to be submersed. These look incredible hanging from trees, ceilings, tents and more. Place them in oversized floral designs too! This large unit uses just 3 AA batteries (not included).
