We use our air pole technology on our
air pole range of tents and a lot of
people are still unsure of how they work,
so I just want to describe an air pole, and
how it works.  Probably the best way of
describing it is it's like an old football. If
you take the bladder out of an old
football and pump that up, it blows
up to a much larger size than the
football. It's the skin of the football
that keeps its shape and allows the
pressure.  It's much the same as with one
of these air poles.  This is
just one of the sample poles that we
have but, there's a Boston valve on there
which is where you pump it up, and inside
there's a bladder.
Now the bladders oversized and it's made
of a thing called Thermoplastic
Polyurethane or TPU.  So this plastic has
excellent characteristics for stretch, it
can stretch up to quite a large size, but
the sleeve that the bladder goes into is what gives it its
shape and keeps its size. They've
also got some flexibility and they are strong
and they'll spring back into shape. So what I'm going to do here is, I'm going to
pump this bladder up and show you that it
can grow a lot larger than what the
actual air pole is.  So you can see
already it's getting larger.
So we thought we'd have a bit of fun and
see if we could burst this, and you can see,
look how big it's got compared to its
normal size.  So you can see it's never
going to burst inside this tube.  I'm a bit
puffed because I've been pumping for ages.
It's still under 5 psi by the way.
