The team is divided into two groups: two signalers and the rest are builders.
The object is to develop a signaling system not using sound, but using other body language. Two lines are placed 6 ft. apart. The signalers must stay behind the lines. There are cards with sentences on them. The cards are about the size of a CD. The signalers will know that the only good cards are those that the first word starts with the letters A – M. Starting at the lines, the builders put down the cards to make a trail connecting the lines. There is a small object midway between the lines that the trail must go around both ways.
And to add one more part on each side of the object, the cards must be turned 45 degrees relative to the direction of the trail. Of course, only the signalers know about the trail having to go on both sides of the object and having to turn the cards 45 degrees. Points are given for meeting all three criteria and completing the trail in the fastest time.
