How to make sharpie stay on plastic?

I got bored, and I thought my iPhone case looked dull. So I covered it in white nail polish and let it dry. After, I copied this design onto it:

(If you can't see it, its with sharpie markers) I LOVE IT! But I think that it'll come off onto my hands when I hold it. After the sharpie drys, if I put a top coat of nail polish on it, will it smear or come off or anything? If so, is there any way I can make it stay?

What are quick and easy ways to make money in middle school?

I'm saving up my money for the iPhone 5(or 4s) because my phone is the iPhone 3GS and its really slow and doesn't have a front camera or face time and stuff like that. I really want it soon because my phone is on the verge of breaking. The sim card keeps falling out, it dies really fast, and the headphone jack is broken. I would like a variety of options so I can do more than one thing to get money fast. I'm not a big fan of cleaning but I already do jobs around the house but that won't get me a new phone. It will be about 240 with the upgrade since I have 60 from my birthday. I just recently decided I wanted a new phone so that's why I have like no money.

What do snow plow drivers do when its not snowing?

I have a quick question. What do snow plow people do for work during the months when there's no snow? I know this seems like a dumb question. There's a girl in my class who said her father drives a snow plow. She seems to always have new clothes and she has an iphone so they must be able to afford it. Or do they just get paid so much during the winter that they don't have to work the rest of the year?
