I have lubricated the ball-bearings of two hand spinners (the anti-stress toys) and contrarily to my expectation the time they keep on spinning has been divided by four.
One fact I have noticed, the rolling bearings now makes almost no more noise at all: they were really noisy before.
I am trying to explain myself why/how the energy in the two hand-spinners would dissipate so much faster ? It is contrary to my intuition.
Any idea ?
When I say divided by 4, it is an estimation:
I have an anti-smoking anti-stress technique that involves a short meditation, and I was using two hand-spinners, one in each hand for a duration of roughy 2 minutes, a bit more, (repeated numerous time for one year or so).
But after lubricating them this afternoon with WD-40, the duration falls to 30 seconds at most.
