you know you can do some amazing things
with rubber Johnny I know look at this
ball I’ve made just using rubber bands
isn’t it good mate I was thinking
something a lot more exciting than that
like what like this bungee jumping and
this is how they test the rubber ropes
these elasticated Bungie ropes are the
only thing between you and certain death
so they’re tested daily bungee jumping
was inspired by the people of Vanuatu in
the South Sea Islands who in a
centuries-old ritual use vines to jump
with death-defying precision from wooden
platforms if you jump here though you’ll
be pleased to know that these rapes are
military shockcord
the same cord that’s used in missile
launch tests inside the cord is made
from 380 strands of Malaysian rubber
with a cotton outer core and a polyester
cover the crew will check each rope
manually every single day and the ropes
are decommissioned after around a
thousand bounces once the cord is all
hooked up it’s time for a test bounce
the test uses ordinary gym weights tied
in a bag a hundred and thirty-five
kilograms of them exceeding the heaviest
Java’s weight for extra safety
they go up to the jumping height of 55
meters the rope can stretch up to 3.3
times its length so even at full stretch
you would bounce seven meters above the
ground a bungee jumper wouldn’t stretch
it to the max though so the clearance
would be even bigger the weights show
that everything is in order and now for
the final test with a human subject here
we go some jumpers won’t jump until
they’ve seen the pros do it first
bungee experts George has done over 200
jumps but even he still gets the willies
3 2 1
bungee as the Rope kicks in George is
traveling at over 70 km/h yeah
that’s a puss
