It is a well-known fact that bamboo can grow very fast.
Some species can grow up to 89cm/day (2.91 ft/day).
Each stem has nodes which grow at regular...Show more intervals.
However in some dense bamboo bushes there is no space for the nodes to grow at the same place.
This inspired us to make the Bamboo puzzle.
There are six stems with 5 nodes each.
The challenge is to put the stems in a triangular box with the lid closed. The space in the box is restricted so that no node can touch another at the same height.
There is only one solution.
