Even though fidget spinners on the average are fairly cheap toys, why not keep your kids busy this summer by having them make their own, teaching them simple engineering in the process? This YouTube tutorial uses cheap materials and doesn’t use bearings. It also has a nice “green” vibe to it because you can use all recycled materials like the water bottle caps that are used in this one.
This is a great way to keep your kids busy for a few hours and then keep their hands busy for days after as they play with it.
