SCIENCE FAIR WINNERS

Girls receive recognition for
disposable diaper experiment

THEY DIDN'T quite get back the money they spent on
three kinds of disposable diapers and assorted other sup-
plies, but Crofton House student Maya Lang, of West
Vancouver, and her partner Kathleen Fairey of Vancouver,
were happy to take home a $25 gift certificate and a gold
ribbon for their entry this April in the Vancouver/Lower

Mainland Science Fair.

Their project, entitled Diapers,
was entered in the intermediate
physical sciences category.

It involved two experiments, the
first to compare the absorbency of
three leading brands, LUV’s,
Huggies and Ultra Pampers, and
the second to invent their own ab-
sorbent — yet biodegradable —
diaper.

To test the relative absorbency
of diapers the girls poured 61 ml of
colored water on the inside of the

diapers and then sprinkled them _

with a teaspoon of baby powder.
They turned over the diapers

and the amount of powder that
came off was their measure of the
absorbency.

Repeating the experiment six
times, they came up with consis-
tent results showing that LUV'’s is
the most absorbent, followed by
Huggies and Ultra Pampers.

’ The diaper that the girls came up
with consisted .of a layer of
biodegradable plastic, three
sanitary napkins, cotton batting,

two sheets of gauze, a chemical
substance that turns water to gel
and a sheet of cloth on top.

“The absorbency was not that
great, but I think we showed that
the diaper companies with their
resources and technology, should
easily be able to make a good
biodegradable diape;,’’ said Lang.

Having missed the entry date,
three Collingwood School students
participated in the fair as exhib-
itors, but were not eligible for
prizes. - 4

One of them, Grade 5 student
Jaime Tiampo, did a project con-
cerning magnetic suspension in
cars, which received favorable
comments.

The fair took place at
Sutherland Secondary this year,
and was a prelude to the Canada
une Science Fair held in May at
