Abstract
Se describe el comportamiento de un pájaro bebedor y también el de un pájaro solar, una variante iluminada y sin agua del pájaro original. Se proponen algunos experimentos que puedan servir para motivar a los alumnos a descubrir, siguiendo un método deductivo, las bases científicas del funcionamiento de ambos dispositivos.
Palabras clave: Máquina térmica; Humedad relativa del aire.
