The balloon has a loop underneath, you then let 2 kids (A and B), hold a thread between them, take a second thread, feed it through the loop, once around the thread between A and B, back through the loop and hands the ends to kid C and D. If any of the kids let go, the thread will unwind and the balloon is free.

I don't really get it. Why would the AB thread go off if any one of the CD let go?

Because the CD thread is the only thing stopping the AB thread from pulling back through the loop.

Ah, you beat me to it - that's exactly the arrangement I posted on the site.
