The document describes a proposed business idea for a glow-in-the-dark hockey puck called Light a Puck. The puck would be made of clear rubber with an internal circuit and LED lights that poke through to allow the shape of the puck to be seen. The lights are rechargeable, allowing the puck to be reused. This product aims to address the problems of not being able to see black pucks at night and current glow-in-the-dark pucks not having the right weight or brightness. The proposed solution is that Light a Puck would have the weight of an official puck and brighter, rechargeable LED lights for longer glow. The target market is hockey players who train at night.
