Hi, I'm Josh Clark and
this is Brain Stuff.
Today we're going to answer
this pressing question,
how many balloons would it take
to lift you off the ground?
Let's start with the basics.
One liter of helium
has the lifting power
to raise about one gram of
matter off of the ground.
So if you go to say the
zoo or an amusement park
and you get one of
those balloons that
are about a foot
in diameter, they
can hold something on
the order of 14 liters.
Which means that it
can also lift 14 grams.
Let's say you weigh 50 kilograms
or about 110 pounds, that
means you weigh 50,000 grams.
Which means it would take about
3,500 balloons to lift you off
of the ground.
Add another 500 balloons so
that you rise pretty quickly
and there you go, you're flying.
Now, say you weigh something
like 100 kilograms, which
is about 220 pounds, double
the number of balloons, 8,000,
and you're up in the sky.
You're dodging birds
and planes and you're
causing like air disasters,
and all sorts of stuff.
You probably shouldn't
actually do this now
that I think about it.
But if you can get your
hands on 8,000 balloons
and you're a 220 pounds
with the wherewithal,
I don't think I could stop you.

there's plenty more
where that came from.
