Divide into two to four groups. Have them hold hands and line up parallel to each other. Everyone faces the back of the room except the person in the front of the line.
Flip a coin. If heads, they send a “pulse” by squeezing the hand they’re holding. The person at the back who raises his hand first wins. Negative points for the team that raises their hands on tails.
Lift one, two, or three fingers. Students should sent that number of pulses. First team with student that raises hand with one, two, or three fingers at the end gets the point.
Nicknamed ‘Electric Jenga’. Play either variation 1 or 2. The slowest team or the team that gets the # incorrect pulls a Jenga piece. Team that makes the Jenga tower collapse loses extra points.
