Az egyszerűbb módszert választottam:

"Effect observations
The effect begins to be observed at partial vacuum pressures of several hundred pascals (or several torrs), reaches a peak at around 1 pascal (0.0075 torrs) and has disappeared by the time the vacuum reaches 1×10−4 pascals (7.5×10−7 torrs) (see explanations note 1). At these very high vacuums the effect of photon radiation pressure on the vanes can be observed in very sensitive apparatus (see Nichols radiometer), but this is insufficient to cause rotation."
