[Phys-L] bc's fidgit spinner

[bernard cleyet <bernard@cleyet.org>]

one of them.  

OK,  I did it!   Wow,   many different ones (purchased [1] four).  


So go to (for the raw data) :  

http://cleyet.org/spinner/bc's/  


(includes, also, new header and as .txt file)  


You will note the time I bumped the table (purposely).  

I  will (eventually) post analysis.  


Two of the fidgets have rather smaller moments of inertia.  The one used is 76 g  (others are: 43, 72, and 29)  

I think the one I didn’t purchase is utubed — music (tone?) “synched” w/ ‘phone.  [$20 instead of 10]

bc,  …   again thanks Bryan Mumford.  

[1] Microsoft writes purchase(d) is pretentions, use buy(ought)  My favo, is plan ahead, because I often plan behind.
