Youngest, meanwhile got curious and wanted a cube of her own. Knowing her interest might not last, we came to an understanding. I would pay for half the cost, if she could, using brother's, to learnt the algorithm of solving the cube. Youngest would finish her homework, then waited patiently for brother to pass her the cube while he goes for his basketball training. For 4 days she spent 2 to 3 hours twisting and turning. Following instruction on Youtube, writing down the algorithm. Finally, a week later, she got The original Rubik cube. I under-estimated her but it shows, anything is possible with great determination.
