Image of a liquid-filled green balloon with an XR-Symbol stenciled on it in red chalk paint, against a background with a vertical gradient from deep dark blue to black. At the top, “Rebel against data centers” is written in big red letters. A white arrow points from the text “Hydrogen peroxide, Acetic acid, Salt & Acrylic Paint” towards the knotted neck of the balloon. At the bottom, in smaller white letters, it reads “This acidic mixture corrodes the concrete foundation. Hydrogen peroxide causes steel rebar to rust. Salt speeds up these processes”
