Sensory Builder: Color Changing Fiber Optic Lamp is great for promoting calm and focus or for other multi-sensory use.  This color changing light includes a silver base with color changing crystals inside which create a mesmerizing effect as light shines from the tip of each fiber optic strand and the "crystals" in the light's base glow and change color. This battery operated light can be used as a calming presence in a classroom, bedroom or therapy space.  It also makes a fun party light or even a comforting night light.  The possibilities are endless.  The color changing lamp requires 3 AAA batteries (included with each lamp) and is ideal for ages 8 and up.
