I got a call from the property master of the TV series CSI. They wanted to buy some rust dust. I have no idea when this episode will air so I don't feel bad posting an outline of the plot. A man dies. The crime is solved by opening up his stomach and using magnets to find that he was killed by drinking too much rusty water. I told the property master that rust dust is not magnetic. I did find some iron oxide I bought from a chemical company to use as rust dust was magnetic. It had been anneal so it didn't work for the my "Rust Dust Sprinkle" technique. The iron oxide I bought is a very fine powder. I plan to send him some rust flakes, which he can grind up, if they need something larger to show up on camera.
As promised here is the result of the double galaxy.
