I guess I got to do it again! It was my Grandad's birthday so I got him to solve a cube, about 40 years ago when the cube was first released, both his children (my mum and uncle) learned how to solve it but he never did, maybe one day he can actually learn to do it properly, but at least he has done it once (even with precise instructions from me).
cube used: MoYu HuaMeng YS3M Ball Core
