These vials, common on most ordinary levels today, feature a slightly curved glass tube which is incompletely filled with a liquid, usually a yellow-colored ‘spirit’ (a synonym for ethanol), leaving a bubble in the tube. A spirit such as Ethanol is used due to its very low viscosity.
Why are spirit levels Green?
A Spirit Level is a tool used to indicate how parallel (level) or perpendicular (plumb) a surface is relative to the earth. Typically, the vials in a spirit level are a yellowish-green color with additives for UV protection and maximum performance in temperatures ranging from -20 degrees F to 130 degrees F.
What is a torpedo level?
A torpedo level is a type of spirit level that is an essential tool for any professional working in tight spaces. The body of the level is made of either metal or plastic and contains two or three tube vials. These tubes, or vials, contain yellowish-green additives and are used to determine the surface level.
What size level is best?
We prefer to use levels with 0.0005″/1″ accuracy or better. On a 48″ level, that gives us a maximum error of +/- 0.024″, or 3/125″. However, less expensive and smaller levels like torpedo and pocket models often fall short of that mark.
What was used before spirit levels?
The Egyptians used a plumb line with an “A-frame” to help ensure each stone used in construction was level and the Romans used water filled tanks as a primitive spirit level.
What is level bar?
It consists of a small glass tube containing alcohol or similar liquid and an air bubble; the tube is sealed and fixed horizontally in a wooden or metallic block or frame with a smooth lower surface. The glass tube is slightly bowed, and adjustment to the horizontal is indicated by movement of the bubble.

Are Longer levels more accurate?
Two things to keep in mind: the longer the level, the greater the accuracy — and that when working in cramped quarters, an overlong level is useless. Some levels also have a vial set at a 45-degree angle to the length of the tool. This allows you to determine proper position for braces and other angled pieces.
How much fall is half a bubble on a level?
Depending on how the level is built, if it’s tilted so that one of those lines is in the middle of the bubble, the angle is about 1/4 inch per foot. For a 2-foot long level, one end would be 1/2 inch higher than the other. Colloquially, “a half-bubble off” means a person is out of touch, stupid, crazy, or drunk.
