Huh. So I imagined the ball on the table immediately as a colorless glass sphere on a white table. Before I even read the prompt to push the ball in my imagination I had already placed my index finger on the ball and was rolling it around it place like a fidgit so I just tapped the ball to push it with my index finger so the person who pushed the ball was me (non-binary) for reasons that I was already interacting with the ball anyway. I imagined this in the first person so I didn't really see myself in full. The ball itself was baseball sized and rolled a short distance, stopped and wobbled after being pushed.
I didn't think about what the table was made of but the ball itself was glass that was smooth and cold to the touch. The table was square, waist height and dining room table sized. The room these objects were in was featureless and visualization was instant upon reading.
