Tangentially related. I used to go out on boats a bunch meant years ago. Lost a moto Razer when they were still kinda new. Was bummed, but learned. So I bought what at the time was a kinda nice Nokia(one of the first bar phones with blue tooth) and put it in a condom and tied it off. Could still use it fairly normally, and there was enough air to keep it floating the few times it fell in. Caught on with some of my cohorts, others got a very expensive lesson in laughing at me.
