One features as many as 100 reflected
images. Another requires 600 watts of
power.
They both are portable participatory
paraphernalia.
Seven portable exhibits, designed for
the Ann Arbor Hands-On Museum,
were placed on public display yester-
day at Rackham Assembly Hall.
THE EXHIBITS demonstrate con-
cepts from the sciences and the arts,
according to a statement issued by
Lorraine Nadelman, University
associate professor of psychology and
co-director of the exhibit.
One exhibit, titled "Everyone Is You
and Me," allows two people sitting
across from each other and peering into
a partially silvered glass to see them-
selves (as in a mirror), each other (as
through a window), and a composite of
both images. This is accomplished
through manipulation of a dial which
adjusts the intensity of the light.

Court
reinstates
PBB
kawsuit
LANSING (UPI)-A divided
Michigan Court of Appeals yesterday
reinstated a suit filed by former
Michigan Chemical Co. workers who
claimed state health officials failed to
protect them from PBB contamination.
In reversing a lower court's dismissal
of the suit on a 2-1 vote, the appeals
panel said workers should not have to
choose between their jobs and their
health.
THE SUIT-filed by workers and the
Oil, Chemical and Atomic Workers In-
ternational Union-accused the state of
Michigan and the state Department of
Public Health of negligence in their
handling of the toxic fire retardant
which was once manufactured at the
now-defunct Michigan Chemical plant
in St. Louis, Mich.
It said officials failed to take the steps
required by law even though they knew
or should have known PBB was an
"immediate and serious" hazard to
workers' health.
Michigan Chemical employees ex-
posed to the substance have com-
plained of a variety of ailments. Many
said they have a hard time getting new
jobs because employers wanted no
responsibility for the future health
problems.
Their suit was dismissed by a court of
claims judge who said the state was
protected by governmental immunity.
In overturning that ruling, the ap-
peals panel said intentional misconduct
would not 'be covered by the gover-
nmental immunity shield.

200watts of electrical power to light. se
PARTICIPANTS, especially young $1
children, often find it difficult to keep
all three bulbs lit at one time because of
the great amount of energy needed to
spark 600 watts of power. This is
similar to a "black out," exhibit volun-
teer Carl Berger said, at which time
electric generators are unable to
produce and maintain the required
amount of voltage.
The "Duck-Under Kaleidoscope" is a
boxed-in structure composed of three
mirrors arranged to form an isosceles
triangle, according to Berger. A person
looking into any one of the mirrors can
see as many as 100 reflected images of
him or herself.
The exhibits, which were funded by

rnational Year of the Child, were built

udents, and community volunteers.

,500.
The exhibits will remain at Rackham
