The Albi GLOWING BALL lights up in rainbow colours and glows in the dark, providing endless fun for children. It also includes rules for 23 games and other tweaks. This special ball with a reflective holographic effect and phosphorescent elements works on the principle of refraction of light, thanks to which it shines iridescently in the light. The blue pentagons of the ball have a special photoluminescent effect, so that when illuminated in the sun or under a light bulb, they subsequently glow in the dark. The effect lasts about 15 minutes, and the whole process of “charging” with light needs to be repeated. Thus, the ball does not require batteries or charging.
