Break up the room into two groups. (You can keep it in one if there aren’t enough people for two)
Line them up, preferably female-male. One person then needs to lie down on their back. The next person will lie down next to the first person but with his/her feet facing the opposite direction. They should be close together to the point where their heads are touching.
Lay people down alternating them in the same manner. Everyone’s feet should be facing out from the center. Then,have everyone raise their arms in the air and flex their wrists so that they make a flat surface. Tell them that it’s very important to keep their arms stiff.
Take the first person out of the line,have them stand up, help lay them down on the first set of hands. This person will be passed all the way down the line along the hands. The people lying down need to keep passing them down the line without letting them fall. (Someone is needed to spot this game because usually they will start to waiver every so often.) It’s important for the person being passed to remain stiff as well so that it’s easier to pass them.
Once they reach the end, that person is helped off the human zipper and they will lie down next to the last person in line and become part of the zipper. The second person toward the front of the line now will go through the same process and then the third and so on and so forth. If you have enough people to do more than one line, you can have races between the “zippers.”
