.....is a simple proposal for a recreative /creative "game" with gravity and inertia .
A bar/rod ...playing in the same time the lever(age) and pendulum motion (possible "self" rotation...) ...let's say , as :

The lever/bar can rotate ( fixed horizontal pivot ) and slide in the same time...playing as a rotating/tumbling variable / spring pendulum ?!

Why can't I self-running the Milkovich double pendulum?
Hi Kolbacict !
We can play a game with "two sticks" ( lever+pendulum) or with a "single stick " (lever-pendulum ) .
With a single bar/ rod ( spring assisted...) acting in the same as a lever,spring- pendulum,inclined plane we have a minimal design/arrangement easy to test.
Your query about a possible "self" running of a (lever+pendulum) /Milkovic's double oscillatory pendulum , can be related with a test , replacing pendulum with a spring -pendulum , as:

You can test , also :
