courses in school, usually 3rd or 4th grade. In August 2011, an American company released a children's toy called Kikbo based on the Jegichagi. Construction Traditionally, a jegi is made by taking a coin with a hole through the middle, and a sheet of hanji paper. The paper is folded in half, the coin is placed in the middle of the folded paper, and the paper is folded several times again with the coin still inside the paper. A sharp object is then used to pierce a hole through the paper, also passing through the hole in the coin. Each end of the folded paper is then inserted into the hole, and the ends of the paper are unfolded and torn into strands. A simpler method is to place a small pile or two or three coins in the centre of a 25 cm square cut from a plastic bag or tissue paper. The paper is bunched around the coins, and the coins are tied in place with string or a rubber band. The loose part of the bag or paper is then cut into strands. The most important factor of good jegi is its weight, which should be around . If it is too light, it is very hard to control jegi since it falls to the ground before the next kick is ready. However, if it is too heavy, it is hard to kick the jegi high enough. Gameplay Players kick the jegi into the air using inner side of the foot. The winner of the game is the player who kicks jegi the most times without letting it fall to the ground. Other ways to play include: Heollaeng-i (헐랭이) Use of the inner side of the foot to kick 'jegi' while the other foot balances the body. The foot used to kick jegi should remain in air without touching the ground. Ttanggang-aji (땅강아지) Similar to #1; however, the foot kicking jegi touches the ground each time before kicking again. Left-right foot (우지좌지) Similar to #2, but both feet are used to kick jegi alternatively with either the inner surface of both feet (or one inner and the other outer) Apchagi (앞차기) Use of the top of the foot to kick jegi. Dwitbalchagi (뒷발차기) Use of the top lateral side of the foot to kick jegi. Kijigi (키지기) Each lift of jegi must be higher than one's own
