Q. What is in a spirit level?

Answer

A spirit level is a tool that may be used to determine whether or not a surface is level. Framed in either plastic, wood, or metal, it holds a glass tube filled with liquid and has an air bubble in the middle of the tube. A level, sometimes known as a bubble level, can also be referred to as a spirit level. This is due to the fact that the liquid contained within the vial is a mineral spirit. The hue of the mineral spirit solution ranges from yellowish to greenish since it contains chemicals that prevent the mineral spirit from fading when exposed to UV light and colorant.
