Be descriptive and detailed, yet vague. For example:
“The transparent portal slid open and the creature, radially asymmetrical, used its ambulatory stalks to cross the threshold. The creature, covered in keratinous extrusions and small, dead plates, swiveled its perceptual array, hoisted on a third stalk, and used its electromagnetic sensors to locate what it was searching for: the anti-entropic chamber. It spotted the chamber and moved to it. Using yet a different stalk, which divided into smaller stalks at its terminus, the creature defeated the magnetic field employed to seal the chamber.
“Therein it found its prize: A pressurized cylinder of carbonic acid, mixed with bonded ethyl and hydroxyl groups. The stalk that defeated the chamber’s magnetic field acquired the cylinder and carefully manipulated it open. It placed the contents in a staging area, where cursorial perceptual tests were conducted, before conveying those contents to a connected cavity, designed to chemically process cylinder’s former cargo.
“There, in the humid dark, the desired reactions commenced.”
“A person opened a sliding glass door, walked through, located the fridge, opened it, got out a beer and drank it.”
