Fidget Spinner
Flick the spinner, watch it go. That's it. That's the tool.
Spin it
Grab the spinner and flick โ the speed of your flick carries through as angular velocity, friction bleeds it away exponentially, and the counters track rpm, total rotations and spin time. A strong flick lands over 3,000 rpm and runs about a minute; the button gives a standard push for the flick-impaired.
A small monument to 2017
For a few strange months in 2017 the fidget spinner was the most wanted object on earth โ patents disputed on television, airports selling them at triple price, schools banning them wholesale โ and piliapp's virtual one became a quiet legend of that era, which this page cheerfully salutes. Physical spinners run 3,000-5,000 rpm on ordinary bearings, and record ceramic-bearing spins exceed twenty minutes.
The claimed focus benefits never found much scientific support โ the research on fidgeting aids is thin and mixed โ but as a harmless outlet for restless hands, no notes. This one is tuned to spin down in about a minute so the meeting eventually gets you back. For fidgeting that produces something, the tally counter counts and the Pomodoro timer focuses; for pure chance-toys, the Magic 8 Ball is one shelf over.
Frequently asked questions
How do I spin it fast?
Flick along the rim rather than through the centre โ the physics reads your pointer's angular velocity, so a fast arc at the edge beats a hard straight drag.
What is a good rpm?
Ordinary flicks land 1,500-2,500 rpm; 3,000+ is a strong flick. Physical spinners peak similarly, whatever playground legends claim.
Do fidget spinners actually help concentration?
The evidence is thin and mixed โ the focus claims were marketing more than science. As a harmless habit for restless hands, though, no objection.
Why does it slow down and stop?
Simulated bearing friction: an exponential decay plus a small constant drag, tuned so a good flick runs about a minute โ like a real spinner with adequate bearings.
