Before any more "How silly, he had to make the iron look appealing to get people to do something healthy" comments arise, I invite readers to consider how many of you have paid $15 or more for a BPA-free glass/stainless steel/double-walled plastic reusable water bottle. Did you really need that over a simple plastic water bottle? Or a cup? My guess would be no. But you did it because you're trying to get yourself to drink more water, and perhaps that requires getting a vessel that looks or feels aesthetically pleasing to use habitually.

Disclaimer: I bought an Ello glass bottle from Target less than 48 hours ago for this very purpose--to make myself drink more water. I don't consider shaping iron into the shape of a fish all that different.
