The objects can be random and easy, but I need something that has enough mass so that when it does move to shut the door, there is enough momentum.
Probably... a basketball? But I need it to have a high enough velocity as it moves toward the door to shut it. Meaning employing a ramp of some sort?
And to build up the number of items, I can maybe have it move off the ramp using books or something.
