Lifting a Man with Helium Balloons? | I Didn’t Know That


ever since I was a kid I’ve always
wanted to have a go at lifting someone
off the ground using helium-filled
balloons and today
why dreams come true Johnny I’ve done
the calculations to get me airborne
we’re gonna need at least 30,000 of
these yeah actually rich I was thinking
of slightly bigger balloons and when
Johnny said big balloons he meant big
balloons look at the size of this
thing’s a whopper and it’s going to get
bigger when this balloon is fully
inflated it’ll have a diameter of two
and a half meters and it will hold over
seven cubic meters of helium which is
just about enough to lift seven
kilograms off the ground
we’re just testing this balloon now this
weight is just under seven kilograms and
look at it with Richard tipping the
scales at a very healthy 96 kilograms
the boys are going to need to fill
around 14 of these monster balloons to
have any chance of getting an airborne
everything set everything that is except
the weather while the boys have been
busy in the hangar the perfect summer’s
day outside has been replaced by one
with the wind gusting at up to 30
kilometres an hour
not the ideal weather to fly balloons Oh
you ready for this oh yeah this wing is
got one and it is providing like
anything the guide on Johnny I’m ready
to go off
attaching all 14 balloons in this wind
was proving very difficult and it wasn’t
long before things started to go wrong
oh look at that six leaving the alarm
strong think of the Wright brothers
think of Richland Johnny but try as they
might in this wind the maximum naked
attached with seven balloons and that
just wasn’t enough to keep Richard in
the air for any length of time and here
we go again filling bloom takes a long
long time but that’s dedication for you
and after three to four hours of hard
graft we were ready to fly once more
this is it the point of no return
it’s time to get airborne right all the
balloons are inflated are you ready rich
I’m ready here we go now can you feel
that
I have now attached yeah that’s quite a
target Lee we did this experiment to
find out how much helium it would take
to get Richard off the ground and the
answer is an awful lot I’m just a little
bit light footed now oh right these are
the last four balloons and he’s gonna go
go
in the end we used 18 balloons which
hold approximately 96 thousand litres of
helium
well nearly Richard maybe you’d get a
little higher if you stopped eating so
many pies oh really jealous
