Specifically, the experiment used was that of many leds arranged in a metal bar, which effected a circular motion through computational aid, such leds during its rotational movement, gleamed different positions and intervals smaller than retinal persistence (reaction time of the brain necessary to distinguish two images), creating the sense of movement and allowing the writing words in the air. The proposal was applied to a class of 1st year Engineering and the data obtained by video recordings of classroom where the demonstration was presented, were analyzed in the light of the theory of playful experimentation and conceptual development by students.
