Density of Different liquids in a bottle what does it do?

Hey i did this awesome experiment!!!!  Can water Float?  It actually can cause the density of each element is different.  This experiment can help with oil spills because the oil when you do the experiment is on top and if they skim it off it will take the oil off and save the fish. 

What You will need:
Red and blue food coloring
Measuring cup
1 cup of corn syrup
Clear glass bottle
1 cup of vegetable oil
1/2 cup of water
1/2 cup of bleach

Mix the red food coloring with the corn syrup and pour into the bottle
Next pour the oil in the bottle
Then mix the blue food coloring with the water and pour that in
You will see the layers forming, do you notice they do not mix.
Now pour in the bleach, it only touched the blue water amazing right.
