Most of the children who come to STEMland can solve 3×3 Rubik’s cube.
We now have bought 4×4 Rubik’s cube and this made a few of the students curious. Now 3 children from class 7, 8 and 9 can solve 4×4 cube. This only took them for about 3 weeks to figure out how to solve it.
Following is a video of a child (padmanaban) from 7th grade solving 4×4 cube. He solved it under 2 minutes.
