Hook ideas… hmm.
Okay, say it's a normal ice machine (no weird ITS GONNA EATCHU noises), except with absolutely no internal mechanisms. It still dispenses 20 kg of ice per day. Forget the lack of ice-making machinery — that breaks conservation of mass! Where's the ice coming from?
Is this thing draining the polar ice caps? Freezing the moisture out of the air? Drawing water from the sea, or the nearest river, or someplace altogether stranger? What if, when they analyze the water, they discover that it's coming from some obscure aquifer? One, perhaps, that can't be reached any other way? What if it's draining the water out of one of those lakes under the Antarctic ice? What if the ice isn't even from Earth? Imagine the Foundation having to cover up the Galileo probe's imagery of a giant inexplicable ice quarry on Callisto…
Or, if you don't like those angles, take a closer look at the lack of machinery. How is this ice made? Is the machinery invisible? Is it altogether nonexistent? Is the ice just deposited here from another dimension? Is this thing actually a little hole in the laws of physics that attracts water like carrion attracts flies, and then freezes it because why the hell not?
Or you could take those sounds and make them more interesting. Why does this sound like teeth? Is it something's mouth? Something's, er, excretory organs? If so, why does it look like an ice machine? What possible benefit is there to that? If there isn't one, well, why does it do that anyway?
Or maybe it doesn't sound like teeth. Instead, what if it sounds like icebergs calving and glaciers melting? What if, under the sounds of splintering ice and dripping water, a close listener can sometimes make out a droning human voice? If so, what are they saying? Reading climate statistics? A list of the physical & chemical properties of water? A list of the physical and chemical properties of… something else? Names and dates? Names and drink preferences? Names of people paired with a ludicrously-precise measurement of the percentage of their body mass attributable to water?
Your answers to any of these questions, properly developed, could give the article sufficient hook. Pick your poison.
(…yes, people, this is how my brain works. >_>)
