AB  - This  paper  discusses  the  oscillations  of  a  spring  (slinky)  under  its  ownweight.    A  discrete  model,  describing  the  slinky  byNsprings  andNmasses,  isintroduced  and  compared  to  a  continuous  treatment.   One  interesting  result  is  thatthe  upper  part  of  the  slinky  performs  a  triangular  oscillation  whereas  the  bottompart performs an almost harmonic oscillation if the slinky starts with ”natural” initialconditions, where the spring is just pulled further down from its rest position undergravity and then released.It is also shown that the period of the oscillation is simply given byT=√32L/g,whereLis  the  length  of  the  slinky  under  its  own  weight  andgthe  acceleration  ofgravity independent of the other properties of the spring.
