Lately, I've been failing so hard at water marbles, but I felt the thumb of this one was passable.

 For a base colour, I painted (from the thumb) Barry M Nail Paint in Cyan Blue, ASOS Paints in Olivia, Blue, Orange, Blue lol. I reversed the order for the other hand (not pictured).
 I also suck at photographing marbles clearly. Sorry about this, y'all.
While I was doing a water marble not so long ago (not this one, the offending marble involved the infamous Miss Sporty Clubbing Colours Yellow nail polish) something interesting happened. A ball of the yellow nail polish sank to the bottom of the plastic cup. I wouldn't have cared but about five minutes later it had actually managed to eat it's way through the cup and there was nail polish filled water /everywhere/. Messy cleanup, that was. Anyone else found anything similar?
