DIY: Turn an empty plastic soda bottle into a spray paint gun

I'm a strong believer in the power of spray paint. It can transform a flea-market find into a work of art. It can revitalize everyday items around your home. But with a finite selection of colors and a high price tag, store-bough spray paint can limit the size and scope of your project. But what if you could mix your own pain colors and apply the paint with a homemade sprayer? YouTuber The Q has released a tutorial outlining the necessary steps to convert an empty soda bottle into a spray paint gun.
