How to make a simple homemade thermometer with a glass bottle or jar, a drinking straw and a bit of clay. Inside we only put water, but it is better to dye it so we can see it better. In my case I will use red wine, because it is more colored than with the ordinary food coloring powder. You can use Coke too.

A thermometer is an instrument used to measure temperature. It operates based on the principle that substances expand or contract in response to changes in temperature. This expansion or contraction is measured and converted into a numerical value that represents the temperature.
There are various types of thermometers, including traditional mercury thermometers, digital thermometers, infrared thermometers, and thermocouple thermometers. Each type has its own advantages and applications.
Mercury thermometers consist of a glass tube filled with mercury, which expands or contracts based on temperature changes. Digital thermometers use electronic sensors to measure temperature and display the result digitally. Infrared thermometers measure temperature by detecting the infrared energy emitted by an object. Thermocouple thermometers use the principle of thermoelectricity to measure temperature.
Thermometers are widely used in various industries, scientific research, medical settings, and everyday life to monitor and control temperature. They play a crucial role in ensuring safety, quality control, and comfort in various applications.
