Macro cutaway view of ent_archimedean_screw illustrating helical trapping and gravitational lift. The central wooden shaft with a broad threaded helical blade rotates inside an open wooden pipe sealed with waterproof pitch. Successive trapped water pockets are clearly visible, contained between the spiral blade and the inner cylinder wall, being forced upward along the axis without spilling backward. Hand-carved wooden pegs and bronze fittings are visible on the structural rings..
