4. Holding one of the netting pieces
08
taut with both hands, dunk it into the
paper mush and then pull it straight
up so it catches some of the paper
mush in it.
5. Lay the second piece of netting on
top of it and then place both together
on a stack of newspaper. Press evenly
over the entire piece of netting with
the palm of your hand in order to
push out as much water as possible
and compress the paper mass.
6. Now lay the paper mass with the
netting pieces on a dishrag, lay a second dishrag on top, and press it some
more between the two dishrags.
7. Then, carefully remove the netting
and let the paper dry thoroughly on
the heater.
Explanation:
Your homemade paper is, of course,
not as nice as commercial paper.
Among other things, you would have
to add ingredients such as chalk to
make it heavier and denser, along
with other materials to prevent ink
from bleeding on it. If you use printed
newspaper as your raw material,
the addition of laundry detergent
makes your paper brighter, because
it dissolves the printer’s ink from the
paper fibers. In paper production, the
process of removing printer’s inks and
dyes is called “de-inking.”
Experiment
Gasoline consumption
Automobile fuels are made from
petroleum. The supplies of this material are gradually declining, while the
price is constantly rising. That’s why
fuel-efficient cars are becoming more
and more popular. Also, combustion
engines (just like heating systems)
produce large quantities of carbon
dioxide gas, which accumulates in
Earth’s atmosphere and contributes to
global warming. How much does your
car consume?
You will need: pencil, paper.
Procedure:
1. When your parents are filling the
gas tank, note the number of miles on
your car’s odometer and the amount
of gas put in the tank. For the period
during which you are making your
experimental observations, ask that
the tank always be filled to the same
level when filling up (just to the point
that the gas nozzle first shuts off, for
example).

2. Note these figures when a parent
09
15
or other adult fills the gas tank the
next time, or ask to be pro-
vided with the data.
3. Calculate the average
amount of gas your car
uses per mile (gallons
divided by the cor-
responding number
of miles), and what
the fuel consumption is
per 100 miles (consumption per mile
multiplied by 100).
Explanation:
If your car uses around 4 or 5 gallons
per 100 miles,
that would be
about average
these days. Still,
if you burn a
gallon of gas
it creates a
little under 9
kilograms (20
pounds) of climate-damaging
carbon dioxide gas. In the future,
cars might be taxed according to the
average quantity in weight of carbon
dioxide that they emit per kilometer.
This should be as far under 200 grams
of carbon dioxide per mile as possible.

Experiment
Expensive dripping
faucet
Every American consumes, on average, well over a hundred gallons of
water a day. In Europe, the average
consumption is a little over one third
of that. It’s important not to waste
drinking water, especially due to
wastefully running or dripping water
taps.
You will need: measuring cup, watch,
pencil, paper.
Procedure:
1. Open a faucet just
enough for the water to
drip slowly.
2. Place the empty measuring cup beneath it and
note the time.
3. Check on the experiment from time to time.
Once the measuring cup is
almost full, note the time
again. Look at the scale
on the side of the cup to see how
much water is in it.
4. Turn off the tap.
5. Calculate how much water per hour
dripped out of the faucet, and how
much it would be if it dripped like
that for a week.
Explanation:
If even just 1 liter drips out per hour,
that’s 24 liters a day, or almost 9,000
liters — over 2,300 gallons — a year!
Even if we had
plenty of water to
waste, purification and distribution of water
require energy
too.
