⚠️ PUBLIC HEALTH WARNING ⚠️
We've built something dangerously scrollable.
It starts in the sunshine at the top of a tree and doesn't stop until you hit the roots. 121 questions. 19 diagrams you can poke. Absolutely no celebrity gossip.
Side effects may include:
🌳 Knowing why leaves go orange
🌳 Explaining sap to your kids at teatime
🌳 Correcting your mate who reckons roots go as deep as the tree is tall (they don't)
🌳 An irrational urge to put wood chip round everything
It's written so a five-year-old can follow it, with the proper grown-up words underneath for everyone who's pretending they already knew.
Put the news down. Doom-scroll a tree instead 👇

Leaves, sap, rings, roots, fungi and the four walls a tree builds round a wound. 19 diagrams to poke at. Warning: highly scrollable.
