Hello, everyone!
I'm conducting an experiment in a lab
and while setting parameters, this question came to my mind.
Are ping-pong balls hydrophobic? (They are made out of cellulose)
And if sesame oil or grease is coated on the surface, do they become hydrophobic?
Thanks, as always![Approve :approve: :approve:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/approve.gif)
