RAINBOW MILK
Question: Which brand (Palmolive Original, Palmolive Antibacterial, AJAX Super Degreaser , Ivory Ultra )of dish liquid is most effective at breaking down fat molecules?
Hypothesis: We predict that the most effective brand of dish liquid will be the Palmolive Antibacterial. Each soap has its own combinations of ingredients. We are predicting that the antibacterial agents will break down the most fat molecules since it also kills germs.
Materials:
1.Flat tray(cookie sheet)
2.Food coloring(3 or more colors) 3.Whole milk(do not use low fat milk) 4 .Liquid soap(dish liquid) 
|
Safety Procedures1.Do not consume the dish liquid.
2.Do not drink the milk after the experiment. 
|
Procedure:1.Pour the milk into the tray so it covers the bottom and you can not see the tray.
2.Add about 6-8 drops of at least three different food colorings onto the milk in different spots. 3.Add 1 drop of liquid soap(dish liquid)onto the drops of food coloring. Watch it now! 4.To clean up, just pour the rainbow milk down the drain(don't drink it). |

The Science behind it
For this experiment to work the dish liquid has to effectively breakdown fat molecules. When the dish liquid breaks down the fat molecules the color spreads and creates a cool design. This happens because Magnesium Sulfate in the winning dish liquid controls the thickness of the milk which makes the colors spread. The Palmolive Original is the only dish liquid that has the Magnesium Sulfate so, that's why it worked the best by spreading out the food coloring
Conclusion
In, conclusion we reject our hypothesis because we predicted that the Palmolive Antibacterial dish soap would breakdown the most fat molecules in the whole milk, instead the Palmolive Original did. This happens because the Palmolive Original contains Magnesium Sulfate which controls the thickness of the whole milk, and that's what makes the food coloring spread out the most.

About Ella and Claudia
We both enjoy playing sports and learning about science. Also, we enjoy some of the same hobbies. We wanted to do the science fair because we like learning new experiments. Ella and Claudia have known each other since 1st grade.
