Harmonic skipping
I'm doing standing waves with my HL class and was wondering if anyone had ever skipped the second harmonic on a skipping rope. If I read my own blog then I would know that they have. But anyway I searched second harmonic skipping on you tube and found this video which claims to be the first (not true). So I wonder if anyone has skipped the third or forth harmonic, the frequency is going to be pretty high but double Dutch skippers can skip really fast. Notice how they do this without moving their bodies. If they had to actually jump up and down the rate would be limited by gravity but this way its down to how quickly they can move their legs.
