Thermal illusion

The installation consists of three long metal coils 100 cm, 40 cm in diameter, woven around a central body. On the one hand, the coils will have a lower temperature than the ambient temperature (minimum 10 ° C), on the other hand the temperature will be higher than that of the human body (maximum 40 ° C). In the central part the temperature will be equivalent to that of the environment. When a visitor touches the ends of the reel he will feel warm and cold sensations. but when he tries to touch the central part he will have the sensation of burning himself.
