I don't see what good that nozzle does. While I agree that the nozzle does increase the velocity of the air in the restriction the air will slow down as soon as it passes the nozzle. The nozzle actually slow down the air flow over all. I think it is funny they make a big deal about don't do this at home, we have many degrees. I don't care what degrees they think they have they don't understand the basic of fluid hydraulics and the Bernoulli equation. In short, they have embarrassed themselves before all that know better.

Other than that it is a good example of what a kinetic energy can do.

Good they used an orange ball for that.
