MONGOLIAN GAME: For this game you'll need 2 large cardboard funnels. The opening in the narrow part of each funnel must not be larger than a coin, the opening in the wide part must be large enough to put it on the player's face. Beside the funnels you'll need 2 little wooden bricks and 4 chairs. To begin the game put 2 chairs in a line at a distance of 3-4 meters from each other. Opposite each chair (at the distance of 10-12 meters) put one more chair. Two players compete in this game. To begin with they sit on their chairs with the funnels in their hands. The bricks are at their feet on the floor. As the leader commands: "Begin!" - the players put the funnels on their faces (so as to see the floor only thorough the little opening) and begin to drive their bricks to "the goal" (the interval between the legs of the opposite chair). The player who copes with the task the first becomes the winner. But it's rather difficult to cope with this task, because the players can see only the little space of the floor in the little opening of the funnel, while after each kick the brick drops out of the field of vision. Advice for the leader: watch that the players don't take off their funnels (otherwise the game makes no sense), watch that the players kick the brick and don't drag it.
