Of all things to be used in the bathtub a rubber ducky is probably not one of the most useful devices. Actually it’s really only there for a giggle, but it’s classic so I understand that much. I can almost get an Elvis rubber ducky. After all there are still plenty of Elvis fanatics and he does look pretty funny in rubber duck form. However, flashing LED lights, that I don’t get. That is where I draw the line. The LED lights kick on only once the duck is in water and then it will phase through a series of colors. It is now being sold for £2.95 or about $5.
