Sign of the Day
cooling coil
This sign descriptively shows a coiled pipe used for cooling. It involves two hands: one representing a base or pipe (non-dominant S-hand), and the other (dominant G-hand) tracing the explicit spiral of the coil

Today’s Snapshot
The meta fields are doing real work here
This page turns your sign metadata into a fast, readable fingerprint of how the sign looks, feels, and fits into real conversation.
Dominant hand forms a G-hand (index finger extended); non-dominant hand forms an S-hand (loose fist)
Dominant G-hand traces a tight spiral motion around or in front of the non-dominant S-hand
Discussions about HVAC, refrigeration, engineering, or plumbing systems

Use the numbered steps first, then check the sign anatomy cards to clean up the small details that make the sign look fluent instead of approximate.
How to form the sign
- Non-dominant S-hand palm left, fingers up
- Place S-hand in front of chest
- Dominant G-hand index finger points at S-hand
- Trace tight spiral around or in front of S-hand
- Move G-hand upwards during spiral
Coach prompt
Practice forming the non-dominant S-hand and dominant G-hand. Trace a tight spiral upwards around your non-dominant hand. Add the 'brrr' mouth morpheme

Ensure the spiral motion is tight and clearly depicts a coil. The non-manual 'brrr' can enhance the 'cooling' aspect
Best fit: Discussions about HVAC, refrigeration, engineering, or plumbing systems

Catch the slip
Ensure the spiral motion is tight and distinct, not a loose circle. The non-manual mouth morpheme helps clarify the 'cooling' aspect

Common mistakes: Confusing with 'spring' or generic 'tube'; not clearly depicting the coiled shape
When not to use it: For general 'cold' or 'cooling' concepts not referring to the physical apparatus
Regional note: None known; likely consistent as a descriptive technical sign

How does cooling coil differ from similar signs in BSL?
It differs from 'spring' by its continuous spiral motion and static non-dominant hand, and from 'tube' by the explicit coiling. The 'cooling' aspect is often implied or supported by non-manuals.

This sign for COOLING COIL (dominant G-hand tracing spiral around non-dominant S-hand) differs from 'SPRING' (dominant G-hand often bounces or twists up from non-dominant) by its continuous, tight spiral and static base. It differs from a generic 'PIPE' or 'TUBE' (often flat B-hands forming a cylinder or C-hands showing diameter) by explicitly depicting the coiled shape. The 'cooling' aspect is often conveyed by context or a 'brrr' mouth morpheme
