Visualise (picture, imagine, whatever you want to call it)
I ignored this portion of the instruction because it was unnecessary to answer the question of what might happen to the ball if it were pushed by someone. I didn't visualize anything until moving on to the spoiler questions. Even then, my brain mostly went "nah, we'd just be making up something to fill in details irrelevant to the question, don't waste the energy".
Oat for most things. Extra creamy.
Almond for a fewthings. Like I prefer almond in a bowl of cereal. Silk has an unsweetened one with extra protein that is my go to.
