Feel free to add to these if you find anything cool

Just looking at the rust tutorial brought back some memories.

I used to make a rust solution by simply leaving screws in water, then painting the rusty water onto plastic. Worked well but these days I use chalk.

That rust one was good. I really liked the side pipes tutorial... Great Idea for a thread.
