New YouTube Channel “Akiyuki Brick Lab” is launched

I launched the new YouTube Channel “Akiyuki Brick Lab” . I upload videos of my models in Akiyuki Brick Channel and I show some experiments in Akiyuki Brick Lab. I uploaded following two videos. Lego: An attempt to distinguish soccer and basketballs by their rolling traits I try to sort the two kinds of LEGO balls, soccer balls and basketballs, without a light sensor. Rolling-down speeds of the balls depend on their groove features. Lego: Which is the strongest axle? (torsional stiffness test) I compared the torsional stiffness of five Lego axle samples.
