Making money online at 16 years

Hi, I am trying to find a way I could make some money at my age without leaving the house.

Have a ton of free time after school that could be used for making money. Also I have around $400 on my regular bank account that could help.

I am looking for something easy to do without having to know any difficult skills or having to show my face.

Please type only ideas you (or someone close) have experiences with.

Thanks.
