Why are barns red?

… because of the nuclear fusion in dying stars.

Stars die when they stop nuclear fusion. Nuclear fusion stops at the 56 nucleon cut off, at which point the star falls apart, sending loads of bits and bobs into the universe. 

What bits and bobs does it make with those 56 nucleons? There’s one element— with which you are already very familiar— that has 56 protons and neutrons in its stable state: iron.

What super common, and thus cheap, pigment is used in red paint? Red ochre, aka iron oxide. Yep, stardust.

It’s no wonder why farmers have historically chosen red paint. It was an economical choice due to the abundance of iron oxide available in nature, thanks to the stars. Now, even as more low-cost color options are available, I’d guess that farmers continue to paint their barns red out of tradition. What a lovely thought.

It’s a joy discovering the interconnectedness of our universe. One of the best ways to make these discoveries is through a humble garden.

A seed containing hundreds of peppers inspires awe.

A flower following the sun inspires wonder.

A moth pollinating while we sleep inspires thanks.

Tending your own beautiful garden can improve your health, awaken your curiosity, and transform you into an active caretaker of our earth. We make it easy to get started. What are you waiting for?!
