Speed up the ball bearing

[john west]

After more than a few spins, the free fidget spinner that we got from a newspaper offer now seems more noisy than when we first got it.

I read not to put oil in the ball bearings because that will slow it down.

Would a *tiny* drop of WD40 (according to NASA not a lubricant, but a moisture displacement agent) or a *tiny* drop of silicon oil likely to speed things up?

I have no idea to what you refer. Brian

WD40 will dry out to become a thick wax. A thin normal oil might work, such as sewing machine oil.

fitting some decent quality bearings would be the first thing

WD40 is white spirit. It removes any lubricant present

The first thing would be to bin it. You only get 1 life, don't piss it away.

Try powdered graphite (used for locks)?

More likely to build up and cause skidding. NASA found this in the

1960's. There are quite a lot of rolling element bearings used in satellites for solar panels and attitude control wheels. Indium plating was one of the things used, also low volatility oils, but I am not very up-to-date.
