Vito L., Aug 27, 2018 : Hi folks, Today I’m bringing you a fun little story from a recent conversation I had with Jade T. I was talking to @David Y. and he thought the community would appreciate this one. For those of you who don’t know, Jade’s one of the industrial designers at OnePlus, and always a good person to talk to when you need to convert a product idea into something commercially viable. With a talented industrial designer like Jade, the end product gets to look and function like the original product you had in mind. So, it was no surprise when Jade told me about a test he used while designing the Mirror Black version of the OnePlus 6 – a test he called the Waterdrop Test. Here’s how it works: take a single drop of water and apply it to the back of the OnePlus 6 Mirror Black. Now take another drop of water and apply it to a non-absorbent surface (the surface of your desk, on a dinner plate, etc.). Notice the size of the waterdrop. Is it flat like a frisbee? Or does it bead like a marble? The difference, as Jade explained, comes down to the “wettability” of the surface. On an ideal surface, or one where the surface is (among other things), rigid and extremely smooth, the water droplet will look similar to the one depicted in the header. Why is this significant? Just close your eyes and run your fingers over the Mirror Black surface – the smoothness gives you that extra-premium hand feel, while the subtle curve and rigidity makes the phone easier to hold and more resilient to impact. Jade conducted the water test on over 100 Mirror Black prototypes before selecting the one you see today. I hope you enjoyed this insight into how the Mirror Black came to be.
