Business Planet takes a look behind the scenes at the LEGO Group headquarters in Billund, Denmark to see how new LEGO bricks, figures and other pieces in development are put through their paces to test their physical properties.
LEGO tests the pieces to make sure they don't break during play. They are dropped repeatedly from a height of 1.5 meters to ensure they don't shatter on impact.
LEGO DUPLO toys, which are destined for younger children, are subjected to a bite test, to make sure pieces cannot be chewed off by inquisitive toddlers.
The toys are also crushed by a one-kilogram weight during the impact test to evaluate the durability of potential weak points.
All pieces are subjected to considerably higher forces than is legally required to make sure they are robust enough for even the roughest child.
