Bottom shelf, the bottle with the blue cap placed on top as a marker to show where. Apparently in that spot, when left long enough, it freezes so absolutely slowly that it manages to produce almost perfectly clear ice.
The fridge was given to me from a hotel I used to work for. The fridge works perfectly, I'm not even sure why he bothered to replaced them all, but I ain't about to argue with a free mini fridge ya know.
I'm sure people are gonna wonder what's on the top shelf, those are repurposed Ensure protein shake bottles, washed out and refilled with V8 juice. Its a shame those bottles are typically disposed of, they're mighty rugged, but it's difficult to get the Ensure smell totally out of them, so I figured tomato juice/V8 ought to do the trick, which it does 👍
Edit: The door hinge is on the right side on this one, for anyone extra curious. And of course, your clear ice mileage may vary wildly from one mini fridge to the next. This one apparently has no temperature setting, it just happens to be preset right at freezing temperature, just barely though. The other bottles around that spot are still liquid, those don't tend to freeze often.
that does nothing except changes the starting temperature of the water. it might also precipitate any impurities like salts, calcium, chlorines, etc out if you're using tap water.
if you want clear ice use distilled water, slow chilled from top to bottom. you can usually achieve this by using a plastic igloo lunchbox with the lid taken off.
