Britta Riley wanted to grow her own food (in her tiny apartment). So she and her friends developed a system for growing plants in discarded plastic bottles — researching, testing and tweaking the system using social media, trying many variations at once and quickly arriving at the optimal system. Call it distributed DIY, or Research & Develop It Yourself.

And the results? Delicious.
