Wet the head of the Drinking Bird, and place a full glass of water near it so that when the head tips forward, only the beak comes in contact with the water. Most Drinking Birds work without adjustment! Sometimes a small adjustment to the pivot point of the bird is needed. Carefully move the metal clip up or down the glass tube, (ca. a millimeter), until the Drinking Bird just balances in a vertical position. 23cm This is not a toy and not for use by children.
