I've heard about an experiment with a very simple setup where you experience a feeling of weightlessness while sitting on a chair. I heard this on a podcast but I can't remember the details or the name of the phenomenon. I only remember that you do something or that something is done to you while you sit on a chair that gives you a surprisingly real feeling of weightlessness and that this something is a pretty simple procedure.
What is the name for the experiment where you experience a feeling of weightlessness while sitting on a chair?
