The Fiber Optic Tranquility Tunnel is an ideal place for overstimulated children, providing a secure and calm location to decompress from any over-stimulating environment. The interior is lined with a plush, fiber-optic-light infused carpet, which twinkles through a rainbow of colors AND is soft to the touch. It does a remarkable job in absorbing ambient noise from the surrounding area, aiding in de-escalation. There is no electricity in the fiber optics " only light " which makes it safe and cool to the touch.
