It seems that fidget spinner has boom unexpectedly, left the earth. Hand spinner also becomes electric bulletin board in the Arduino built but there was a thing that began to evolve into a high-tech one.
If you jump on the space station where the gravity is very low ... What is it going happen?
This time, astronaut Randolph Bresnik challenged. Please check the videos.
While spinning the spinner, you can see the full range that people also turn around. Mr. Bresnik talks about spinner to be turned in outer space.
When the spinner floats, the rotation speed of the center rotation axis and the outer arm part becomes equal, which reduces the friction of the bearing. So all the spinners turn into one unit.
Indeed, it is certainly true if it is a place with little gravity it seems to be turning forever, but that does not mean that the friction of the bearing has never been lost.
It is a hand spinner that rotates with centrifugal force because there is a weight arm on the arm, but on the ground, it is a double-edged sword that causes friction on the reverse and gives a load to the rotating shaft.
Even in a casually playing toy, I got a deeper understanding of the mechanism as a result of having played in space.
