None of this dangerous stuff for me. Any of the girls remeber French Skipping? Or sometimes just called 'Elastic' (or in Leicester-ese - "Laggy".)
You got a loop of sewing elastic, probably about a 6 or 7 foot length tied into a loop. Two people stood facing each other, far enough apart for the elastic to be stretched around their ankles, with their feet 12-18" apart. Then another person had to jump in and out of the elastic loop, in various ways - I think it went "inny, (both feet in the loop), outy (both feet outside the loop, astride it), inny, onny (landing with one foot on each long side of the loop), inny outy off (jump away to the side). Everyone did this, and then the elastic was raised a few inches to mid-calf, and it was done all over again, then raised again etc, so it got progressively harder to jump high enough. I think it tended to get impossible at waist height.
I think there were other variations which involved crossing the elastic over in the middle - all a bit cat's cradle.
And skipping of course. These came and went in trends - one day someone turned up with a long rope, or an elastic loop, and then we'd do nothing else for a week or two.
