Â Â I’ve been working in the lab again to finish up the distillation of the oak leaves. To pull the essence of the leaves from the alcohol we set up a condensing chamber which evaporated the heated steam of the alcohol and let it drip into a flask. leaving the oils behind Â because they will boil at a higher temperature. While getting the temperature stable I was struck by the “tears” of condensation in the tower as the liquid crept across the glass, very pretty.
These tears correspond to the Sun and the Moon, where the upward motion of the drops in the moon may indicate separation, while the downward motion in the Sun might indicate reflux.
