The filling of the Plexiglas composite panes consists of two fine grains, one of which is larger and coloured (blue). In the cavity there are firmly glued, funnel-like locking strips. By turning the board, the grain masses slide and trickle and flow at different speeds. As a rule, “like to like” joins together: bigger with bigger, heavier with heavier, so that layers are formed.
