expº 2 progress

This is the second set of experimentation I did, and now significant results can be observed.
I made 5 plates, each of them set up in different conditions.

In the first plate, I passed a 5V current though the agar. Throughout the growth, colonies started to grow separately from each other, very condensed and isolated.

Unlike this next one, where it was kept within room light/temperature. The growth was vast and 'messy'.

This next plate was kept in total darkness during the whole experiment. The result is somewhat similar to the plate with electricity.

This one was kept under heat produced by 2 small tungsten bulbs. The growth was very fast and spread uncontrollably. After a few days, the bacteria stopped growing - maybe too much heat/light? There was a lot of condensation in the plate.

expº 1 update

These are the results of the first experiment seen in the previous post.
There was a difference in growth between the plate with current and the one with no disturbance.
I turned the current off one week after the plate was set up. At first, small colonies started to appear, isolated from one another. After I removed electricity, the growth became more uniformed like the first plate shown below.

Here are a couple research studies about electricity and bacterial growth that you might find helpful.

A similar project was done in the 2009 California State science fair project.

Progess of 1st expº

Bacteria has started to grow and is visible in most of the plates. There does not seem to be any difference between Tz and T.

Experimentation

Here are some pictures of some experiment.
I am trying to run electricity through agar in one of the petri dishes. I have already deposited some bacteria on the agar and covered the 5 plates. Now let's wait and see.



The copper wire used to run current in the plate.










Tz - Toilet water with electricity.
T, T - Toilet water without electricity.
F - Fridge door handle.
C - Control. (the plate where no bacteria, distilled water on agar.

I have concentrated on looking at remote environments where people leave something behind, and seeing it evolve in that environment. The environments can be objects, places, surfaces that people use as a means of indirect communication. Every once in a while, someone will leave their ideas/identities in that environment. Therefore it lives and evolves on its own.
We walked around Washington Square Park, going into Bobst NYU Library, then up to 6th Avenue and to the Gimbel Library in the Parsons building.


1 - This picture shows posters put up on walking lights posts. High environments where people struggle to find spaces for their stickers to communicate with the pedestrians.


2 - Cement is an environment where identities can live forever, without any interference from the real world.


3 - Communication through signatures.


4 - A sidewalk used by skateboarders where every wheel of the skateboard leaves its mark as it grinds through.



5 - Posts that are used by dogs. Site-specific environments where dogs mark their property, leaving a layers of identities that will last and continue to evolve.


6 - This door shows how an object can be used universally the same way, we can see the scratches over the bar that the push of the door leaves with time.


7 - Here it is the same concept where hands are put on a wall next to a door.


8 - A drinking water fountain where the water escapes but sometimes leaves things caught in the drainage. These objects that people leave behind are parts of them that start living within this specific site. Here, a nail is alone waiting for other objects.



9 - Posters are mediums where people can communicate.


10 - Again, a sticker on a desk where people leave notes.


11 - A table cutter leaves traces of all the papers used.


13 - Desk study areas are also places that are used by different students at different times. Therefore, it is interesting to see how they use that table to communicate with each other indirectly. The table becomes an environment where these notes speak with each other.


14 - This is an end of a stairwell of a fire escape. The door at the bottom is locked. Objects can be found such as a balloon, a newspaper that is one month old, and a bottle...


15 - Toilets used constantly and the automatic laser flusher is not working.


16 - Urinals are also places where people write and leave notes for others to read.


17 - This is a railing next to public toilets, we can notice the part where people lean and sit on it near the end where the paint is gone.


18 - On the street, bikes get stolen and all that is left for good are the locks.


19 - Graffiti is also a way for people to communicate through walls that become environments.


20 - We can notice gum thrown on the floor, however, there are places where they are more present, like the entrance of a subway station. When people spit out a chewing gum, they leave part of themselves in that gum. Then it creates a growing environment.
