Electrostatic sprinkler diameter 35 cm

description

One of the poles of the voltage generator (see SKU 1403, 1139, or van de Graaf generator) can be connected to the spherical end of the sprinkler and the generator can be activated. The sprinkler will begin to rotate on its axis, in the opposite direction to the trend of pointed edges.

We will connect thesecond pole of the generator to the sprinkler, the sprinkler will rotate on its axisin the same direction. Amazing.

Solving this issue requires a correct analysis of the law of conservation of rotational momentum.
