This is a modified version of an Israeli children's game. Everyone stands in a circle and holds hands and sings, while moving around "Oogah, oogah, oogah, ba ma'agal nachuga, nistovevah/nistovevet kol ha yom ad asher nimtzah makom, lashevet, lakum, lashevet, lakum, lashevet lakum, lashevet ve lakum! When it says lasehvet everyone bobs down and when it says lakum they get back up. After the first one, get everyone to hold hands with the person next to the person next to them, and repeat, after each time getting everyone to hold the hand of the person next to the one who they were previously holidng hands with. It becomes quite difficult.
