Craft kit to make a classic bouncy ball that lights up and flashes on impact. The set includes two moulds, two light-up cores and eight sachets of colourful powder. Simply place the light-up ball in the mould, close it up, and then pour in the powder to build up several colourful layers. When full, submerge the mould in cold water to set the powder. Within five minutes the ball will be ready to bounce. The kit includes enough materials to make two light-up bouncy balls.
