[SCRIPT] How do I make a chair move?

[goodcap]

I had no idea it would be this difficult to create such a thing haha.


I don't know if any of you have seen the Paranormal Activity movies, but there is this scene where a kid is on a small bike riding through the house and a chair starts moving a little bit to block his patch.

That's what I need.

(I got this idea from a recent custom story, but I forgot it's name. It literally did what I want so I could just copy it, but I can't find it anymore. It was perfect..)
