Can I take my iphone scuba diving?

I have an iPhone 5c, and it's in a lifeproof case. I've been swimming with it, in the pool and in the ocean, and even cliff dived with it and there weren't any problems. I'm going to be scuba diving, which will be about 35 ft deep underwater, will it be ok to bring my iphone down for pictures? Will the depth be a problem?

Ways to earn money without an allowance?

So I'm 13 years old. My parents used to actually pay for stuff I want but now just recently I asked for an iPhone 5s but they said I had to pay for it, and I know what most of you are thinking. My parents want me to be more responsible with money and learn to save but I don't have an ACTUAL way to earn money. I don't get an allowance because my parents believe that kids should help around in the house without expecting something in return. I've told them already I don't have a possible way to actually work for money and I've already told my parents and they keep saying "well you need to find a way to earn money, we're not going to pay for this phone to see how responsible you are with money." Can you guys leave some suggestions on ways to earn money?

How should I ask permission for a mac?

Before answering, keep this in mind:
- I'm not asking my parents to buy me a mac. I have saved money for this and have been wanting to upgrade my computer for a while. It's a mac mini, so they aren't concerned about my responsibility w/ the mac [ie: had I bought a macbook where I could potentially lose it]. Money also isn't a pressing issue, (my parents have iPhones).
- I intend to buy a mac for Logic Pro and the ease of use w/ the operating system. Trust me, I have considered other audio production tools from FL studios to Pro Tools, but after reviews and watching videos of them in use plus recommendations from teachers and friends, I have found Logic the best to suite my needs. If you are here to detest the macs, I suggest you leave.
- I will not lose anything switching to a mac. I mostly use my current computer for mundane tasks like word processors, iTunes, email, small video projects, etc. All of which will be included on the mac os. Logic will be the first professional software I use. I do not play computer games. The specs will also be an upgrade from my old computer.
- I'm familiar with the os [my school has macs that I have worked on for a music class].
So I have discussed all of the following points with my parents, but they still are reluctant to give me permission. A hackintosh is out of the question because they are concerned I would break the computer [and to be frank, I don't trust myself either]. Should I bring up anything else?

What should I do about my iPhone Lifeproof case?

I have a iPhone 5s and a black life proof case. So today I left it in the bottom of my bag and there are all these scratches and marks on it. I Don't want to deal with that for as long as I have the phone. Is there a way to get rid of the scratches? Or email life proof?
