The craze seems to have started with Youtubers picking them up and doing tricks, or using things like hairdryers to experiment as to how fast they can get them to spin. One Youtuber even knocked out a tooth with one.
That, and the distraction of them in class has led some schools to ban them already. So there is debate whether they would help everyone focus, or prove too distracting for some kids.
If you haven't had the pleading for one yet, you will. You can be prepared and order off AliExpress for a pound or two, but remember you will have a few weeks to wait before it arrives. eBay has them too and you can try searching for a UK based seller there.
If you live in Northern Ireland, fidget spinners have been spotted in Stewart Millars, and I got one this afternoon in Cotters, beside the main post office in Bangor. As of 3rd May they have lots in stock, regular, camo-print and also LIGHT UP!
I've also had a tip off Centra in Wellington Place in Belfast has them. The Spar on the Comber Road in Dundonald is another stockist. The Candy Box in Milisle.
If you have any other tip offs of locations you've spotted them for sale in Northern Ireland, please let me know on Twitter, I'm @rudedoodle (link at top of webpage).
So good luck with your spinner quest! I guess I have to admit I am too old and really can't see the attraction, but I remember the hysteria of Coke yo-yos, so I can empathise with that!
UPDATE: I am giving away the white fidget spinner we bought on eBay before we managed to get one in a shop locally. It will be brand new and not played with. Open to everyone, UK to worldwide!
