We do our best thinking in the shower. It's a lame excuse for wasting water, but it's true. Long showers -- they're our least green habit and we're having a tough time kicking them. So, we realize that we need to exercise a little green discipline when it comes to shower time. We found these shower timers ($19.95) from Ripple Products and we kind of dig the rubber ducky. But ... Is there a better way to do this that doesn't involve a plastic gadget? Or is it worth buying something that would make us smile (and hurry); especially because short showers make us frown? We imagine, if this little ducky motivated us to shorten our showers significantly, that the water conservation would outweigh the rather non-green, frivolous purchase of a silly toy for the bathroom. If the rubber ducky isn't your thing, Ripple has plenty of more traditional looking timers. What are your thoughts? Is this an unnecessary product or a helpful one?
