Day
Two
The local Alabama Hills are amazing to look at. The
low rounded peaks, with incredible bulbous shapes, are
in fact made of granite. In the hot desert conditions,
the granite outer crust is weathered off to ensure that
a smooth, rounded shape is formed. What’s strange
is that the very same granite forms the stunning jagged
peaks that tower over the hills from the nearby Sierra
Nevada. Way up there the cold conditions cause the granite
to weather more by freeze-thaw processes, so forming
a completely different mountain landscape. Actually
you’ll have probably seen the Alabama Hills on
telly, since just about every early western was filmed
there. And it’s still movieland country up here,
with small parts of Gladiator and GI Jane being filmed
here most recently. And soon, you’ll see it on
Rough Science too.
Apart from enjoying the scenery, Ellen and I were keen
to try to launch our parachute from the highest peak
we could safely manage, so that it had the long chance
to free fall and open up. We were assuming that the
rockets that the others were making would be giving
us a few hundred metres of height (ha, ha - as it turned
out), so the main question was to check that the chute
design was stable and that the descent was as slow as
possible. As usual, I was more than happy to clamber
up the rocks, particularly since Ellen was still nursing
a twisted ankle (that’s another story –
for the full sordid details check out her webpages).
A morning of me throwing up (as ever), and Ellen catching
down ended with us feeling pretty good about our chute.
The egg-splattered granite surfaces made us feel less
confident about the safety of our payload. So, back
to the mine to work on that.
We figured that it would be against the spirit of the
challenge to embed our egg in jelly (my idea), or to
hard boil it (my idea) or various other cheats (my ideas),
so we decided instead to give it a natural cushion (Ellen’s
idea). She went out to collect some soft vegetation
that would make a nice wee nest for our precious egg.
The return to the mine also gave us the chance to see
how the rocket designs were coming on, important for
us since we had to design our payload to fit onto them.
The designs of Kathy and Mike were fine – both
were using 2 litre plastic lemonade bottles, so we could
use the cut off base of one of those and simply attach
it loosely on top. Jonathan’s rocket was a vicious
beast – a thin rod of metal tubing that when heated
we expected would sore skyward, bringing down one of
the F-16 jets that regularly buzzed the mine (I swear
they must have thought we were a terrorist group –
how else would you explain such strange comings and
goings in the middle of an abandoned mine). By the end
of the day it had turned out to be a bit of a damp squid,
the air pressure rupturing the seals before it could
escape explosively.
