Nail Polish Cup Decorating

For you my friend, I decided to try this out: Nail polish-water-mug-dipping-thing!
I headed over to the thrift store; no luck finding a plain mug. Next I went to the 99 cents store; wasn't anything different. Last resort was Dollar King, There was not a SINGLE mug.
But there were some clear glass cups. Glass cups and mugs are practically the same thing.
Good enough I guess. Next was nail polish.
I personally don't own any so I had to purchase some. Two bottles: one pink and one blue seemed plenty.

Because it was a large cup, I found it necessary to use a big bucket for the water.

Hypothetically, I'm supposed to drop nail polish into the water and let it bead up to form a cool design.
I'm not entirely sure if I was doing it right or if the water wasn't the right temperature. Possibly the quality of the nail polish?
But then again, the whole set of instructions was in Italian.
And the only Italian words I know are baguette, curly mustache, and Eiffel Tower-- that isn't even Italian is it?
Anyways that just added to my struggle of this all. What ended up happening is the blue polish created a weird film on the water

which just was not attractive on the cup when I swooped it down into the water.

It looked like a complete mess. But no one wants to keep that around.
I went back to Dollar King and bought another glass. And a more expensive ($5) pink polish from CVS. This time when I dropped the polish in it beaded up, and then created a film layer.

At this point I didn't really care, so I swooped it back down into the water to pick up the stuff.
It... it didn't look too great, but it works.

 I was broke from the $10 DIY so I had no choice but to call it a day.
