Physical Interacting, spring like object.

Hey guys

I am trying to make an object that interact with the world when an object is on top of it will push the object down. When an object in removed it will pop back up like it’s on a spring.

in this project, this has to be done via an actually physical way, rather than “faking” it with a collider.

My question is this done on the object or via a blueprinted way and if so how do you go about this?
