Open Question: What is the name of this icebreaker game?

Hi, I'm organizing an "Amazing Race" event for a youth group, where the kids will have to complete challenges to receive a clue. A couple years ago I played a great icebreaker game, where everyone laid on the ground, in opposite directions and side by side (so your shoulder would be beside the feet of the person lying next to you). Then the person at the beginning of the line was passed down the line, until they reached the end and laid on the ground again. This continues until everyone has been passed down the line. Could you tell me the name of the game, and perhaps brush me up on the instructions/rules for it? Thank you in advance!
