How can I move a slinky to show transverse waves?

Why does the bottom of the Slinky remain stationary until the top of the Slinky reaches it?
Held from midair, the Slinky stretches out, quickly reaching a condition known as “equilibrium.” in which the downward force of gravity is balanced by the upward tension of the coils above it. That collapse travels down as a wave through the Slinky. The bottom coils remain at rest until the top crashes into them.
