Five differently coloured diffraction tubes that rotate individually are set into a beautiful high-quality wooden stand. The enclosed fluorescent granules tumble around the inside of the tube as it is spun, shaken and rolled. The granules will also glow when used under a UV light source. Ideal for tabletop or floor play and manufactured with a beautifully tactile finish.
