A few weeks ago I was on a discount shopping site, Massdrop. (buy high-end goods at wholesale and the sells at discount )

They had a category called EDC (every day carry), where they had spinning top for sale.  Similar to the one seen in the movie Inception.

Sometimes I work at home and need something to kill time between phone calls.  So I investigated and found there was something more interesting.  There was another category called fidget spinners.

I bought one and was hooked.  I have now gotten 3.  They are going to be the next big thing.

You will be surprised that many fidget spinners cost over $100.   There are also 3D printed plastic spinners, selling for $3.
