Anybody may easily check
how the drinks packaged in metal cans, when coming out of the can,
run down the lid of the tin and its rim carrying with them whatever
substances are present there by which they may be contaminated.
We suggest doing a simple
test:
|
|
|
1.
|
on
the lid of the tin of a colourless beverage (for example:
tonic water) pour some drops of a coloured liquid, preferably
with water base (for example: red wine, ink, etc.) or sprinkle
coloured powder (for example: paprika, saffron, and so on)
using the substance as a tracer;
|
|
2.
|
wait
for the tracer dry (approximately 2-4 days) if you have used
a liquid;
|
|
|
3.
|
after the
opening of the tin pour a bit of the beverage into a colourless
container (for example: white cup, transparent glass); you
will realize how the beverage has been coloured and almost
all the tracer has been taken off the lid area where the beverage
ran over it.
|
Likewise
to check the effects of condensation formed on refrigerated tins:
|
-
|
pour
or sprinkle a tracer on the lid of the tin as explained in
point 1 of above;
|
|
|
-
|
put
it in the fridge for the time necessary to cool the entire
tin (approximately 12-24 hours). If you have used a liquid
tracer, wait this until has dried;
|
|
-
|
take
the tin from the fridge; you will realize how the condensation
formed on the outer surface of the tin has begum to melt the
tracer and the effects described in point 3 above are much more
evident. |
It is obvious that if
instead of tracer, on the lid of the tin there had been, accidentally
accumulated or deliberately placed there, pollutants and the
tin had been opened for consumption, the consumer would have drunk
a contaminated beverage.
