High Fives is the same warm up as Cross Circle. The difference is that there are two player names (and hence two players) being called at the same time. As the players cross the circle they high five each other in the middle.
One player in the circle chooses a random player across from them in the circle. They signal the selected player by making eye contact, lunging into the circle and whooshing at them. This process continues until there are whooshes flying back and forth across the circle.
One player starts off by clapping their hands (a singular clap), while facing another player. The player mimics the the starting player and the goal is to clap simultaneously. The player that received the applause then turns and claps simultaneously with the next player in the circle. This process is continued around the circle in a series of individual claps built by pairs of players.
