Observations

1

To me this is just water, there is no smell.

2

As you pour the oil in the water the oil started to bubble at the top. When stirring the oil turned into smaller bubbles. It looks as if the oil has placed a thick line of film on the water

3

After pouring the vinegar in the water the only change I noticed was that the water seemed to be a shade darker when added it. The water looks like it is clouded some. Other than the smell a person would not be able to tell there has been something added to the water.

4

After pouring in the detergent the water begin to look cloudy and there is a thin layer of bubbles.

The water and oil mixture seemed to have a “cleaner” look to the water; it had a light brown color. There was still a thin shiny film at the top of the water.

7

The water/vinegar mix had a very light brown color to it but it looked cleaner than the other two.

8

This one has still a light brown color but this seems to have a dark cloud/fog like texture. There also does not seem to have a smell to it.
