There are reports that at 1am this bushfire over ran the town of Yarloop pop 500. Hopefully all evacuated. The fire front is 113km long and the fire is creating its own thunderstorm. Temps have been up to 43 C, winds to 50kph, flames up to 50m
I am in Bunbury on a bush block some 80km south.

Note that this is not a camera picking up infrared lights but true thermal imaging using long wave infrared 7.2 – 13 microns with vanadium oxide microbolometer array. (Visible light is 0.4 to 0.7 microns).

The twin musical Tesla coils are in cages to reduce interference to electronics and increase safety.
One might expect sparks would be from the nearest point to the cage (ie about 8 inches = diameter of the steel sphere). However, sparks can't breakout from a smooth surface of this size unless there is a breakout point. By positioning one at the top of the sphere,  they preferentially go up the 20 inches or so to the ceiling. 
Now 20 inches is not huge but it is in proportion to the exclusion zone for the operator and equipment without the cage.
This is still loud and needs earmuffs if you are close. In actual use you would have powered speakers behind them to provide the backing music track that the sparks are played to.
I can sit between them so it becomes a compact installation that I can setup without help.

Th answer to my previous photo with laser beams apparently emanating from my fingers. The beams of course are striking my fingertips from an external source and become visible when the fog is added from the blue machine on the left.
The lasers are blue multispectral Argon about 14mW, red HeNe 10mW and green diode 9mA visible. It was a bit tricky to run all this keeping my left hand still while operating the fog machine and camera.

There are three Americium sources from household smoke detectors made visible by fluorescence from Alpha radiation. All about 1.0 microCurie and about 1/2 inch (12mm) in diameter. The top one has no phosphor, the left lower one has Strontium Aluminate:Europium 2% (see below) glowing red and the right lower one has activated Zinc Sulphide glowing green. The Zinc Sulphide has a little glow not restricted to the emitter, due to phosphorescence from light exposure some hours before. 
The photographic exposure is about 7 minutes so this is VERY faint stuff.
This is similar to a spinthariscope - more about this later.

This is a high voltage spark onto deionised water. It is perhaps 1/2 inch high and of sufficient power to redden the heavy copper electrode. The interesting part is the point of contact with the water which is a strange and constantly changing purple pattern.
The reflection below shows the bright point of current flow onto the electrode and is brighter than the arc reflection.  In Xenon arc lamps this pinpoint sized spot on the cathode is the bright part not the discharge itself.

I made this display of magnetic levitation - or rather magnetic suspension which has been installed in the Gravity Discovery Centre in Western Australia, I've given the magnet a bit of a spin.  Did I mention the video is only 2 seconds long? The magnet will continue to spin for over 15 mins if I recall. No bearings = no friction.

Mystery Photo #1. Explain this photo in full. It is complex on several levels. I think you will be doing well to explain one fact, a master if you can explain two, and you must have been lurking in the bushes for three.
Note: Like all my photos, it is a single exposure with no photoshopping.
The subject is my son Chris playing cricket with himself. I will give periodic clues if ideas are running out.

I saw a spider last night 50 m away.
If you walk down your drive in rural Australia using a headtorch you start to see things in a different light.  Tiny specks of light are reflected back to your eye.  So lets look closer in the back yard with a powerful LED torch.
The little speck of light is reflected back from the eye of this nocturnal wolf spider. These are not compound eyes like insects but are better performing cup shaped eyes or ocelli some of which have a tapetum lucidum which gives the eyeshine seen with spotlighting.
The first photo shows the surroundings and the second is an enlargement with a tiny spot of light in the beam that moves from time to time, unlike dew drops which are barely seen at a distance.
The last shows the wolf spider.
Another post will follow on - you will need to refresh this post later.

I saw a spider last night 50 m away.
