Lyne Arm question

While boiling a "water run" to clean out the pot still, I noticed something interesting. The lyne arm is down at a 45 degree angle and 14 inches long and 3/4" dia. I didn't have a worm connected, but liquid water and vapor emerged from the arm. Does this mean a worm is even necessary? I realize water boils at a higher temp than ethanol, but I'm wondering about the necessity of the worm here. What did I miss?

Even though some of the water vapor condensed and came out as a liquid, most of it was still vapor. You need a worm/condenser to condense those vapors (you want to condense ALL the vapor).

Also, you should hook up your worm and clean it out too.

The condenser is something I'm going to look into. A friend of mine has a glass column and a glass condenser. All the condensation appears to take place in the first 3 coils of the condenser. If this holds true, than enough copper coil in room temperature air will condense vapor back to liquid. Possibly eliminating cooling water at least in cooler weather.
