Possible ways to estimate temperature

One method of temperature estimation is done by looking at the sky and observing the shades of its colours. By the tone of gray or blue that dominates the sky a trained eye will be able to approximately calculate how cold it is outside (persons with laponian origin are famous beholders of this skill). Another way, which only works in civilized conditions, is to watch cars and the amount of steam that rises from their engines (a large amount of steam indicates a low temperature). The same kind of steam watching technique can also be done by looking at people waiting for the bus (follow the same principle as with the cars). The third technique involves not only the visual part, but also the feeling. It requires snow, since it consists in feeling the texture of the snow and on basis of that estimate the temperature (liquid and formable snow indicates that we are near 0 degrees Celsius). Another way is to step out naked for 3 minutes, then go back inside and measure the time it takes for your skin to recover from the blue tone and for your body to stop shivering (a long recovery time from the blue tones and the shivering means that it is indeed very cold outside). A further way, dependent on technical equipment, is listening to a weather broadcast and trusting what Mrs/Miss/Mr meteorology says about the temperature in your hood (this one means you lay the estimation in the hands of professionals analysing information acquired from satellites). Then finally there is an uncommonly used method where one watches this apparatuses called thermometer where a number indicates what temperature it is (the thermometer will give you a different number depending on if it is exposed to sunlight or not) . Are there other ways estimate temperature? I am eager to know.
