People have come up with iPhone cases that come attached with all sorts of stuff, like extra battery packs, card holders, and even bottle openers. Those seem like reasonable things to have integrated onto a phone case.
But what about a whistle?
It hasn’t been done yet commercially, but designer Sang-Hoon Lee wants to get it made – with the right support and backing, that is. The case is aptly called the Hoo Whistle Case. It looks like your basic iPhone case, except that it’s got a whistle embedded at the top.
It might seem like a novelty to some, but it’s actually a pretty neat safety device. When you’re in trouble and need help or need to get someone’s attention, all you have to do is put the case to your mouth and blow. Nothing works best as a noisemaker than a traditional whistle, yes?
