In this paper we analyze precisely the starting conditions of the motion of a spinning target with the focus on the thermic/aerodynamic effects. We conducted reference experiments with a static bench, where the motion of the target is obtained with the airflow issuing from a pump, and PKer (volunteer practicing Psychokinesis) experiments (with a new portable bench), where the motion of the target inside the bench is triggered by the PKer. The comparison between the airflow speeds around the target in the two sets of experiments showed that the tangential airflow speeds in the PKer experiments were 10 times lower than the required tangential airflow speeds to start the target moving in the reference experiments. The potential bias and errors in the measurement and computation are shown to be minimal compared to the factor given above. Some particular experimental set-up, simulating the hand and the upper body of the PKer in proximity to the portable bench, did not provoke any reaction on the target. These different elements tend to prove that the motion of the target in these experiments cannot be attributed to thermal/aerodynamic effects. The portable bench could be a good way for other labs to try to reproduce and confirm these experiments.
