How would I make a shear thinning fluid with desired material properties?
This might be a stupid question. Let’s say that I need a fluid with flow behavior index 0.38. Do I mix two shear thinning fluids with different flow index behaviors? Do I just dilute with water? Do I dilute logarithmically or does a 2x dilution double the flow behavior index? I can’t find any real resources for this and am getting frustrated. I don’t know the specific flow behavior index, but I’m trying to figure out how to make it when I get there. Any thoughts?

3x3mm sized metal grating for cutting wax?
I'm looking to cut solid candle wax by forcing a metal grating of some sort not unlike these french fry cutters in this picture:
However, the size I'm aiming to achieve is 3mm by 3mm – quite small! What is the best way to manufacture such a tool?
Thoughts and inputs?

Car Knowledge for Engineer
Hi all, I would like to know if anyone has suggestions for where to gain a broad understanding of car knowledge. I am an engineering student in metro Detroit Michigan and plan on working for an automotive OEM upon graduation. What are the best ways to learn the technical side of cars (parts of the car, functionality of each part, etc.)

Question on Ethics.
I’m a relatively new engineer (EIT) and have been practicing for a few years.
I recently started at a new firm and upon starting received a few projects to manage. One of these projects is for a small, local government agency. My company was contracted lump sum (<$50,000) to do preliminary design on a new facility.
I haven’t actually had any discussions with the client, but I have a feeling that they’re using loopholes to avoid a public bidding process for the job, which I think is illegal. I don’t really have any experience with these sorts of things, but I get the feeling that it is a little sketchy.
Are these sorts of things common? Do I have any responsibility here? I really have no idea what I am doing and would like some advice as I don’t feel comfortable bringing it up with my manager.

The Wikipedia article of the day for February 21, 2018 is North Ronaldsay sheep.
The North Ronaldsay is a breed of domestic sheep from the northernmost island of Orkney, off the north coast of Scotland. It belongs to the Northern European short-tailed sheep group of breeds, and has evolved without much cross-breeding with modern breeds. It is a smaller sheep than most, with the rams (males) horned and ewes (females) mostly hornless. It was formerly kept primarily for wool, but now the two largest flocks are feral, one on North Ronaldsay and another on the Orkney island of Linga Holm. The Rare Breeds Survival Trust lists the breed as “vulnerable”, with fewer than 600 registered breeding females in the United Kingdom. The sheep on North Ronaldsay are confined to the shoreline by a 1.8 m tall (6 ft) dry-stone wall, which completely encircles the island. The wall was built originally to protect the shoreline and keep the sheep inside it, but when seaweed farming on the shore became uneconomical, the sheep were banished outside the wall to protect the fields and crofts inside. Because of their restricted environment, the sheep evolved to subsist almost entirely on seaweed.
