Ulumaika. Bowling stone. This 'ulumaika is thought to be a reproduction as the original material would have been stone. This specimen is made from resin and Formica-like material into a disk of thick depth, similar in look to a puck. The two sides are evenly convex. The 'ulumaika bowling stone is the same name as the game it was played. The game of 'ulumaika was played on a kahua (prepared outdoor course) wherein two athletes threw their stone in a similar manner to bowling and the winner was determined by whose stone had been thrown the farthest along the kahua. This 'ulumaika is dark green in colour with an uneven almost porous surface.
