I dropped my iphone 5c in the toilet and i don't know what to do?

I dropped my iphone 5c in the toilet and i took it out as fast as i could. However, the phone was unresponsive to the on/off button and the screen was frozen on the lock screen. I did put it in a tupperware container full of dried rice. Is there anything else i can do to make it work again?

Added (1). And i only had it for a month-i got it for christmas matter of fact. If i bring it back to get a new one, how much would it cost?

Can I record a video on my mac all day?

Basically I want to record my living room as I think we might have some "unwelcome guests" when we're out.

Would it damage my Mac Book Pro? How much HDD space will I need. I know I can save it as a Iphone file but it auto matically saves the Mov file into my movies folder.

Any help would be most welcome.

Added (1). Well 7am till 5pm. So not all day.

What 'present' would you get?

Recently me and my sister were involved in a minor car crash and today we got compensation of £2,900 as I got hurt!
My mum said we can get anything we want ANYTHING at all but just one thing. There's no price range as I wanted to get an iPhone 5s (around £600). The rest of the money will be put towards moving houses.
What do you think I should get, what would you get?
I was thinking a iPhone or new good phone, a new laptop or a camera.
Thank you for any ideas.

Added (1). We get £2,900 each.
@Jan409 I don't mind giving my mother the money as she's my mum.
She said we could have whatever we want but you didn't answer the question:0

How to deal with a two faced boss?

I have a boss that All the time he talks directly to me is nice and very friendly. But when he thinks I'm not around I hear him constantly complain about me. Thing is this is my HR boss. He also started an investigation about me because he thought I was doing something illegal. On top of that he put me under surveillance and had cops at my apartment searching for illegal goods without a warrant. I hae no proof of this just what I heard. For the record I'm not doing anything illegal but he is. What can I do about this? How can I find devices on my iphone that are being used against me?
