See-through sink trap with clog-clearing knob

This PermaFLOW sink trap from PF Waterworks was featured in Popular Science’s Best of What’s New 2008. To be clear, I’ve neither owner nor use one of these, so I can’t vouch for the quality of the product nor for its practical effectiveness. However, I admire the clever thinking that went into the design: the transparency lets you see at a glance how bad the clog is (or if your wedding ring really went down there), and the knob lets you clear it without dismantling the trap. At least in theory. In practice, of course, accumulated grime (or algae, if your trap is regularly exposed to light) might eventually obscure the interior of the pipe, and the rotating paddle mechanism might break down or get fouled with hair. Be interesting to see if this thing is still around in five years, and if so, how the early installations are holding up. [via SlipperyBrick]
