Les Lab | Controlling Light with High Voltage and Aniseed! The Kerr Effect! @LesLaboratory | Uploaded 1 year ago | Updated 1 hour ago

In this episode, let's control light with High Voltage and Aniseed using the Kerr Effect!
Ordinarily, Kerr cells use a particularly nasty and deadly Liquid as the Kerr media. In this episode I investigate a possible safe alternative using Aniseed!
After a little dive in to history including mechanical television and filming nuclear bomb detonations, we take a look at some kerr fluids, and dig up a reference to little known chemical derived from Aniseed! This chemical is responsible for the Ouzo effect in certain beverages, but also has a high AC Kerr constant!
I build a nice Kerr cell from commonly available materials, cuvettes, polarizers, and scrap metal, as well as a nice high voltage porcelain insulator and demonstrate this effect.
