Abstract: A projectile for being thrown by hand and for marking its point of impact, for example for use in "survival" games has a relatively dense resiliently deformable rubber core, compressible surrounding layer loaded or impregnated with a pulverulent marking material, for example colored powdered chalk, and a flexible outer cover, which on all points of it circumference is provided with numerous perforations or apertures. The core provides the projectile with sufficient weight to enable it to be thrown accurately, and the surrounding layer cushions the impact of the core against a player who is hit by the projectile. On impact, the surrounding layer is compressed between the core and the cover, and pulverulent marker is pumped out through the perforations, and deposited on the player who is hit, thus marking the player.
