self made, this video really shows how…. c’mon!!! it’s my new powerball, more like a rasengan ah?!?, www.nsdball.com with gyro that can produce a torque of 20 kg at the max speed … very very cool, i’m not saying that because i’m affliliate with the site or something, it’s really a cool ball ;)
muscles (hope) and fun.
ps: (ps not like post scriptum but more like a whisper ) i’ll show in the future the step by step results, if there are any. yo.
