These young visitors to the Ontario Science Centre are taking a -
preview look at some of the strange cacti in the desert exhibit,
451,„ part of the Centre's new Spaceship Earth Gallery. "Although
the cacti, live snakes and lizards that fill this exhibit were
brought to Toronto from all over the world, they can' -only
survive in desert conditions.

Like the astronaut en 'route
to the moon who` looks back and
realizes the earth, too, is a
spaceship, t'hp,earthbound visitor
to the Ontario Science Centre is
offered a new point of globular
view in an exhibit gallery
-Lopeni'ng this month.
The aim • of the new exhibit
structure is t� illustrate
without alarm, without ominous
warnings — how life on' earth is
governed by a system' of
balances, how this always has
been the -case and always will be.
It draws upon an analogy:
astronauts exist in spaceships
which. stimulate conditions on
earth, but which give them only
those' life support systems

A highlight of Spaceship
Earth will be the water
re -cycling unit. This , intricate
. series of- glass tubing gulps
polluted water and° swishes It
through a series of strange filters
,,ntil it emerges as" pure
drinkable 'water. Some of the
filtration processessimulated are
ones that occur in nature, while
others are processes ,developed
by man.
Buckminster , Fuller has
developed a special Spaceship
Earth map ,which eliminates
most of the distortion foundon
regular _ maps. The Sciei'rce
centre received permission to
use the map and it can be seen in
" the area of Spaceship Earth
dealing with populations and
their various densities, generic
foods and natural controls.
Visitor participation has
always been stressed in' the
Science centre. And,along with
exhibits to operate, Spaceship
Earth boasts a new feAture —
push-agains. Want to learn
something about nitrogen? Push
the Button and a ' short
audio-visual show takes place.
Want to know more? Push again
and the presentation continues.
The Centre's scientists and
designers have' been working on
Spaceship Earth for more than a.
yearand plan to -open the area in
stages. Half. the .exhibits will-0"be
in operation by mid-December,
with the remainder being
completed in the llowing few
weeks.
