Bending Steel with Your Neck | I Didn’t Know That


there is a ribbon of fire running around
the world
it runs day and night it runs out of the
past and into the future
and it feeds the world few among the
millions know this we are the few who
tends the ribbon of fire that ribbon of
fire is of course steel the fertility of
this man-made alloy is staggering it’s
used in everything from containers to
cars from ships to skyscrapers from
aerosol cans to aircraft landing gear
there are currently more than three and
a half thousand different grades of
steel which are made to many different
recipes but whatever the mix all Steel’s
have two key ingredients iron and carbon
the higher the carbon content the harder
the steel but it also becomes more
brittle the trick is to match the right
steel to the right application some are
so soft you need very little force to
bend them whereas others you need a lot
more muscle and for that we’ve brought
in an expert meet Manjit Singh he’s a
professional man of steel who holds
numerous World Records for feats of
strength now we’ve got three types of
Steel here we’ve got a mild steel which
is very soft and easy to bend we’ve got
a medium grade steel and then we’ve got
a very hard steel which is a lot
stronger now Manjit has got a very
impressive way of bending these are you
feeling confident I’m feeling yeah you
ready now I’m ready for a piece of moral
and physical support manjit’s brought
along his grey head Posse but it looks
like Johnny’s the one who needs
reassuring and you’re absolutely sure
I’m not gonna be impaled I’m not
now remember kids don’t try this at home
absolutely fantastic for his next trick
a medium grade steel which is typically
used in the manufacture of cosh Assis
and as a whole 25 percent stronger than
the last bar he bent can he do it you
bet now this is the hard steel this is
the real tough stuff now you sure you
want to do this yes now this is getting
serious
this is high-grade steel which is
typically used to reinforce concrete in
the building industry it has twice the
strength of the original bar and Manjit
has never attempted to bend anything
this tough before just in case you were
wondering how tough this steel is his
one repente earlier or in this case his
one we didn’t she better try the middle
way this is a bit harder there and it’s
physics point physics
