slinky
 
Slinky
The first slinkies were sold at Gimbels Department store in Philadelphia in 1945, and they have been a staple of toy departments every since. Watching a slinky "walking" down the stairs is a rite of passage for most American children. (Untangling slinkies is a rite of passage for most American parents!)
Bonus: they make a wonderful sound when shifted from hand to hand.
