A woman is doing a tutorial on how to do water marble nails using water.  She uses a nail polish brush and dips it in water.  She gives the instructions on how to start with a base coat of nail polish.  Then she puts drops of different colored nail polish on the water surface.  Then she dips her nail into that paint.  She cleans off any excess nail polish that has smeared on the side of the nails with a paint brush and Q-tip.  She finally shares information about herself and her social media accounts.
