Tesla coil sparks
Australian physics dropout harnesses electricity with dramatic results.
An Australian man who describes himself as "a 50-something year old first year uni physics dropout" has an unusual hobby - he makes lightning in his shed. The image above is called The Modern Thinker - see how it was made here
Don't try these at home.
... and attaches them to a motorised arm, which looks like a glowing halo on a long exposure photograph.
He uses Tesla coils to produce arcs of lightning....
One of his most amazing experiments used a motorised Tesla coil to protect a car. See the video here.
... and was used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920's as well as electrotherapy More of Peter Terren's ongoing experiments with tesla coils can be explored here.
Peter Terren has been experimenting with Tesla coils for 35 years. He calls this effect "The Eye of Sauron".
Here he recreates Michelangelo's Creation of Adam.
The Tesla coil was invented by scientist Nikola Tesla around 1891.....
Using a coloured filter gives the sparking and streaming electricity a red glow.
Not satisfied with just having sparks of one colour, the addition of a rapidly rotating colour wheel creates a multicoloured light show.
Peter's Tesla coils produce extremely high voltages - as much as 500,000 Volts.
