Impulse (also known as Pass the Pulse) is a great exercise for teamwork and breaking the ice at the same time.
To motivate teamwork and have fun
Divide the group into two teams. Each team should stand in a straight line, shoulder to shoulder, facing the other team.
The Facilitator should sit at the back of the lines, flipping a coin so that only the last person in each line can see it. If the coin lands on heads, the two people watching squeeze the hand of the person in front of them. This sends an impulse down the line. No one may talk or make any noises. When the person at the front of the line receives the impulse, they grab for the ball, which is positioned evenly between the two teams. The team that successfully sends the impulse most quickly and obtains the ball can send the person from the front of the line to the back, and the process begins again with a new coin flip. If someone grabs the ball without heads being flipped, then they must send the person from the back of the line to the front, so that the team has to win one more round in order to rotate through. Once one team has rotated all members through, it wins.
The two lines of participants sit facing each other and close their eyes. The facilitator takes hold the hands of the people at the front of the line. The facilitator will start the pulse by squeezing both hands at once. When the pulse has reached the last person in the line they open their eyes and grab for the ball.
