Neat little demo to visualize electric field....

[amdx]

Short video showing electric field from different shaped electrodes.

 Just wish he had put is Wimhurst machine on a different table.

Odd video. No explanation of why he\'s using hot castor oil or flour.

Maybe he\'s making linguini afterwards.

It is a very good insulator and flows fairly well when warm.
The dry semolina flour is the equivalent of micro pith balls.

Its a rather pretty demo of electric fields.

Other oils might also work (and other dry powders too).

Making linguini out of castor oil would have other interesting physical
effects.
