A THOROUGH BEATING
Testing of inline skates: in
order to test its durability, each
model has to suffer several
mechanical tests in the lab,
one of which is this three-hour
pressure run. The skate,
weighed with 60 kg, gets hit by
the metal bumps on a rotating
drum (which creates a hell of a
noise!). The procedure is
supposed to simulate 2 years
of average use.
