Soap on a rope
I bought each of my children a soap on-a-rope as a Christmas stocking stuffer (because evrryone has to get one of those as a gift at least once in their lives, am I right?). After an initial confusion and a short TED-style talk from me, they each tried theirs and reported to be super-happy with both the idea and the scent (I bought a selection). Overall, everybody is pleased!
