Very!
The Coanda effect appears to be a first cousin to the Bernoulli effect,
n'est-ce pas?
But what on Earth is a "piezo gyro"? It's a little dingus that's shown
stuck under the dome in the detailed pictures, and something in the
text suggested to me that it's the bit of magic that keeps the whole
body from counter-rotating due to the torque which must be applied to
the propellor. But "piezo"?? Like, you squeeze a quartz crystal just
right and its angular momentum increases? That can't be right...
