Every 60 seconds there is a cunt posting a positive message that they don't live by #stargazer #skywatcher #boobstarer. Love words, agonize over sentences.

Pinecones are one of the best-engineered humidity sensors on the planet, and they've been running this design for 200 million years.
Each scale is made of two layers of tissue that absorb water at different rates. The outer layer swells faster than the inner layer when it gets wet. That differential expansion creates a bending force that pulls the scale shut. Same principle as a bimetallic strip in a thermostat, except the pinecone figured it out 199.99 million years before we did.
The reason is reproduction. Pinecones only release their seeds in dry, windy conditions because that's when seeds travel farthest. Wet air means rain, and rain means the seeds drop straight down into the parent tree's shadow where they'll never get enough light.
So what looks like a party trick in your bathroom is actually a dispersal algorithm optimized over 200 million generations. Open means launch conditions met. Closed means wait.
Engineers at Bath University reverse-engineered this exact mechanism to build building facades that open and close with rain. No motors, no electricity, no sensors. Just geometry and differential swelling.
The pinecone doesn't know it's in your bathroom. It's just running the program.

vocês sabiam???? se colocar uma pinha no banheiro, quando você estiver tomando banho ela vai fechar e quando o banheiro ficar seco, ela volta a abrir
