One may have wondered how well a normal CD ROM can hold up to extreme situations. Often it may be a question as to whether or not it would be a good idea to, say, put a CD in the microwave, or take in the shower. While common sense answers most of these questions, it is always a good idea to find out for sure by running scientific experiments. This series of experiments was carried out to put an end to the uncertainty concerning the durability of CD ROM's.
The test subjects consisted
of a small collection of CD ROM's. Half were randomly chosen to be
control CD's (it is a coincidence that all of the experimental CD's were
Microsoft Internet Explorer CD ROM's). No placebo CD's were needed
as CD's Are not alive, thus do not exhibit the placebo effect (although
this has not yet been tested). Thus the experimental subjects all
are represented in the following picture:
The first experiment was to confirm people's general
thought that CD's are delicate. The experimental subject was placed
on a table right side up, and was rapped sharply with a hammer. No
observable indentation was made, and so the CD was hit harder with still
no effect. finally, the CD was pounded repeatedly with full force, but
it simply defied all attempts to break it. The CD was inserted into
a computer, and the directory structure could still be read (the Setup.exe
file was NOT run for obvious reasons). Not to defeated by a simple
CD, the experimenter placed the CD slightly over the edge of the table,
and hit it were the CD was not on the table, and a piece broke off.
Thus being positively reinforced, the experimenter continued until the
CD would break no more. The CD no longer could be read by a computer
in this state.
The
control was still operable.
This experiment defied our hypothesis of CD's being delicate, thus one may be assured that pounding on CD's with full force is not dangerous to the data in the CD as long as the CD is on a flat surface.
The second experiment tested the effects of the
microwave oven on a CD. The hypothesis was that the CD would destroy
itself and possible the microwave. The experimental subject was placed
on a folded piece of paper, and placed on a microwave with a ROTARY platform
(it could matter). The microwave used was a low power one with a
single setting often used by college students in their dorm rooms.
The door was closed, and the microwave turned on. After about a second,
amazing circular electrical arcs raced across the CD. After about
five seconds, the arcs had turned into smaller confined arcs, and smoking
ensued. When the CD caught on fire, the experiment was ended.
The microwave was not damaged. The CD went into a computer with difficulty
(it had warped slightly), and spinned, but was not read from. The
control was unaffected.
Control:
Thus it would appear from scientific evidence
that CD's should NOT go into a running microwave oven.
The third experiment was to see if the detrimental
effects of the microwave oven also occurred in a conventional oven.
The oven was preheated to 350 degrees Fahrenheit. The CD was placed
on a folded piece of aluminum foil, and then put in the oven. For
about five minutes, the CD appeared to still be in working order, but then
some warpage became evident, and after several more minutes, it was obvious
that it would no longer work. It was taken out of the oven and cooled
with water, then pealed off of the aluminum foil. The CD would not
fit into a computer, and so it was assumed that it was no longer in working
order.
The control was still in working order.
Thus, it can be seen that CD ROM's should not
be stored in a heated oven.
The fourth experiment concerned the combustibility
of the CD ROM's. It had been heard through friends that CD's burned
rather well, and so the hypothesis supported this idea. A gas burner
from a stove was lit and put on "high". An end of a CD ROM was placed
into the flame, and taken out when combustion was achieved. To the
experimenter's surprise, the flame went out immediately after it was removed
from the heat. It was attempted again, but this time kept in the
flame. The attempt had to be aborted because molten plastic was dripping
onto the stove. Aluminum foil was then folded over once, placed over
the flame, and the CD was placed on the foil. After a minute or so,
the CD began melting like in the oven. The edges began to bubble,
but still no flame burst out. A paper towel was lit and placed on
top of the CD to ignite it, and this was successful, but the fire only
lasted for a short amount of time. Several more attempts were made
with wooden toothpicks to light it, but the CD would not stay on fire.
Finally the experiment was ended and the CD cooled in water. The
resultant CD was much more brittle, and very distorted. In some places
the optical foil had peeled away, and in others the plastic had seeped
from underneath the foil, making areas of clear plastic. It was noted
that this method could be used to make very nice modern art, and provided
a use for the Microsoft Windows 95 CD's which accompanied the experimental
subjects. The CD had warped quite a bit, and thus could no longer
fit inside of the computer to test the functionality, and so it was assumed
to be destroyed.
Again, the control was still functional.
This shows that CD ROM's are not as flammable
as may have been thought. They could, if necessary, be used to put
out fires, but given the incredible sticky mess and dangerous vapors that
would result in doing so, it is not advised unless the CD contains software
sold by Microsoft.
