Siato - a popular Filipino game between two or more players. Two sticks are used to play this game. One is about two feet long, and the other one about half a foot long. A small hole in the ground is made where the smaller stick will be placed with one end at the bottom and the other end sticking out. The player will hit the smaller stick with the longer one so that the smaller stick flies to the air. At mid-air, the player then hits again the smaller stick with the longer one. This is repeated three times. Whoever hits it to the farthest distance wins the game. As punishment, the loser will be forced to shout the word "siato" without interruption while running back to the original starting place.
