Polly plans to apply to Penn
State to enter a pre-vet program,
eventually to move onto the Uni

Spreaders are the
most accurate
broadcast
spreaders in the
world. The unique
pendulum action
keeps the spread
pattern close to
the rear of the
machine while at
the same time
providing a
symmetrical
pattern on both
sides.

The pattern allows “back and forth” as well as “around
and around” operation. The “truncated” pattern offsets
inaccurate overlap problems, eliminating streaking.

Ben also was fascinated by how
electrical streams decreased the
friction of a rotating drill bit and
added to depth of penetration.
Ben wondered, could electricity
be used to “move” contaminants
out of the soil?
Ben’s project soon was titled,

Between Texture and The Efficacy
of Electro-osmosis In Effecting the
Removal of Contaminants From
Soil,’’ which won reserve senior
champion at the Lancaster County
Science and Engineering Fair.
Ben obtained eight soil samples
from various teachers, one from
his backyard, and another from a
nearby creek. He wanted to see
how using electro-osmosis worked
on different soil types.
He took the soil samples and
in soil

placed them in a long florescent
light tube measuring about a foot
long, with contacts on each end.
He used alligator clips to book
wires to the tube. Hie wires were
connected to an 8-volt generic
direct current power supply. The
contaminant used was tannic acid,
structurally similar to the aroma
tics such as benzene, toluene,
xylene—gas additives and poten
tial environmental hazards.
The soil was charged
six hours. Ben con
ducted tests at three
points along the tube
every two hours. He
used a gradient measure
to point out the contami
nation at each site. The
tannic acid test kit used
a color comparator to
determine concentra
tion of acid.
What he found was
that soil types affected
how the contaminants
would move in surpris
ing ways. Ben discov
ered that too concen
trated of an amount had
a “seep-back” effect that
was undaunted by the
current flow.
It's possible that
commercial industries
could use the informa
tion gathered about the
use of electro-osmosis
to clean up radioactive
contamination of soils.
Another application
could be to see what
affects the process has
on soil nutrient load
levels.
Ben had help from the
USDA NRCS office to
assess the aspects of soil
science. He read and
researched extensively
on the project, of which
he garnered reserve
senior champion.
Ben intends to go to
college to study for an
environment-related
career. His adviser is
Patricia Wee.
Sarah’s Egg Storage,
Processing Compari-
sons
Sarah, 16, daughter of
Russell and Barbara
Woodling, Landisvillc,
continued a project
begun last year on “A
Comparison of Euro
pean and American Egg
Processing and Storage
Methods: A Two-Year
Study.”
Sarah noted that her
dad, who suggested the
project, learned yean
ago through the Boy
Scouts that a way to pre
serve eggs would be do
boil them for about 10
seconds. Intrigued, she
decided to study how
egg shelf life could be
extended in a variety
of ways.
So Sarah obtained 40
dozen eggs from Sand
er’s Eggs, including 20
dozen processed and 20
dozen unprocessed. She
tried four different tests:
boiling the eggs for 10
seconds, microwaving
eggs for 10 seconds,
refrigeration, and stor
age through a contained
atmosphere technique.
