I bought a chinese jumprope for my kids this weekend at toy r us in WI. The directions on the back said to start with the rope 6 feet off the ground! No, not inches, FEET! I remember playing on the playground at school. The school staff “out-lawed” going beyond the level of thighs because 2 girls went to the nurses office with “goose egg” bruises on their foreheads! Someone in the middle landed on the rope at a high level and the two “enders” smacked heads! Be careful when teaching your youngsters. I don’t remember songs we just chanted what we were doing ahead of the jump so the others could catch us if we were cheating. i.e., If you said “on” you’d better land on, and if not then you messed up.
