 * THE STUDY OF DIFFERENT KINDS OF MATERIALS AND DIFFERENT AGES OF DISAPPEARING INK. **


 * ABSTRACT **

The purpose of this study was to determine how fast disappearing ink disappeared on different surfaces, and which age of disappearing ink disappeared fastest on a napkin. Disappearing ink has chemicals in it that react to the carbon dioxide in the air, which cause the disappearing ink to disappear; the older the disappearing ink, the less the chemicals react to the carbon dioxide, for the chemicals are sort of “worn out” and don’t work as well as they would if the disappearing ink was much newer. On each surface, the ink disappeared at a different rate; it all depended if the surface was an absorbing surface, or if it was one that couldn’t absorb anything very well. Different ages of disappearing ink were also tested all on a white napkin to see if the age of disappearing ink affected how fast it disappeared. It was determined that the different type of surface //did// affect how fast the disappearing ink overall; It was also determined that the age of disappearing ink did //greatly//affect how fast it disappeared on the same surface because of the older chemicals.


 * EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS **

I would have changed the amount of layers of napkins that I used in this experiment. Instead of first using maybe say one layer of napkins, I would have a bigger amount of napkins to ensure that my answer was correct. I think that when I used one layer of a napkin for some experiments, the ink sort of “sunk into” the surface underneath. I think the results might just have been a tiny bit different if I used a bigger amount of napkins. I also would have tried to manage my time better by doing more than two experiments at a time. For future experiments, it would be found interesting to test different ages of disappearing ink on one kind of fabric so that if disappearing ink were to get on clothing, it would be good to know if the disappearing ink would be able to come out of that fabric, and how long it would take. It would also be good to know how long disappearing ink takes to disappear when tested against different types of drinks to see if it can still disappear after being tested against things that could change the result.
