2 foot high kick

This weekend I took my Guests from Japan to see The World Eskimo Indian Olympics; an annual competition held by the indigenous people. This is the two foot high kick; wherein the contestant must leap into the air, kick the ball with both feet and land back on the floor on both feet without falling. After each round the ball is moved upwards about 4 inches, 10cm. This year the winner was able to kick a ball over 9 feet high, over 3 meters high!
