I love this one in Gizmag. Apparently, in Michigan they were using talking urinal cakes to remind people to call a cab rather than drive home during Independence Day celebrations.
When I first saw it I thought about how accurate it might be (thinking that it detected alcohol in your pee of something).
It was a bit more basic than that, being triggered by motion – so just peeing on it.
According to the story, a female voice tells you to call a cab home. It also points out that even if only a few people respond positively to the advice then that’s good.
I’m just wondering what the sound quality must be like, especially coming out of a urinal!
Couldn’t use them on the UK, though. They’d get nicked.
