An elastic multicolored band maybe about 3cm thick. The 'rope' was stretched between two people facing one another around the ankles at a distance apart so that the band was pulled tight and a third person - the 'jumper' would jump in and out and twist inside the band wrapping it around one's ankles and attempt jump up out of the twist landing inside (or outside?) the rope without touching it or if you are to touch it you were to land on the rope with one foot on either side of the rope. The tricky part was to do several twists and jump out of them without tumbling or tripping on the band. I don't really remember if this was something we kept score at (by say how many times one could successfully twist and jump up and land inside or outside the band) or... if we simply danced in it like jumping rope. I do remember how fun it was though!
