Eleven teams held three balloon competitions. One player in each group draws a card, and the other two players use the actions specified in the card to crush the balloon. The card says that two people use different methods to press the balloon (for example, head to head, butt to butt or thigh to butt, etc.). ) Change one player's cards every minute for five minutes. The first three groups with the most explosions are rewarded, and the three groups with the least explosions can be punished.
