You just need to understand critical speeds, resonances, and that you shouldn't suddenly change the speed of the rotors. But in _To kill a centrifuge_ Langner describes some games with pressures as well. Adding random valve openings and closings in a refinery, gas plant, sewage plant, etc. will look like intermittent failures and just as hard to 'debug'. Eventually you'll hit a particularly nasty set. Errant monkeys playing with your PLCs. But it must be a slow day at Tech Review..

You could build something that consumed carrots and autodetected when a rabbit entered, then fired up the juicer. You'd need some kind of refridgeration source for the rabjuice, either ice or dry ice replaced daily or some power supply. Then you would not need to press a button only refill carrots weekly and harvest rabjuice at same time, if refridgerated. (Or visit the station more frequently for fresher rabjuice.) .... cf Simpson's rat-milk episode

I'm not clear: is there glow in the dark cheese? That would be an awesome hack, either fluorescent (GFP) mould or some other chemiluminescent pathway. Some fungi are phosphorescent, right? Is someone working on that gene-cluster? To be served in uranium-glass bowls, of course. (U-glass fluoresceses intense green under UV)

You have limited infoprocessing resources. You spend some on a conversation, its less for driving. Conversations can be more distracting than ethanol. Its pretty simple. I've told my wife and kid to shut up when I'm concentrating on a new route. Know your limits.

If you had better tools, you could more effectively demonstrate your total incompetence.
