No matter how long the slinky is, the bottom of the slinky will stay still (hover) until the top reaches it.

This is a consequence of Hooke's Law. Gravity pulls the slinky down until

mg=-kx

m = mass
g = gravitational acceleration
k = spring constant
x =displacement

And it reaches equilibrium. When the top is released, the potential energy stored in the spring pulls it upward with acceleration

a = -kx/m

Which from the first equation is

a = -g

Which cancels out the gravitation acceleration and results in the bottom remaining stationary until the potential energy is expended.

I didn't know the equations, but I did figure what causes it...
