Are ping-pong balls hydrophobic?

  1. Jan 23, 2013 #1
    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:

    Hi 333cory333! Welcome to Physics Forums!

    What experiments have you already tried? Have you tried comparing the balls with and without oil or grease yet? How can you measure if a ping-pong ball is hydrophobic or not? No one here will spoon-feed you information if you haven't even tried experimenting yourself first. Click on "Rules" above. After you do your experiments and testing, post your results here, along with any of your questions or doubts.

    I still haven't found out a certain answer, but I'm surely progressing!
    Thanks for your consideration :)
