How does the food coloring spread when you put dish soap on a Q-tip?

Milk is mostly water but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. Fats and proteins are sensitive to changes in the surrounding solution (the milk).
The secret of the bursting colors is the chemistry of that tiny drop of soap. Dish soap, because of its bipolar characteristics (nonpolar on one end and polar on the other), weakens the chemical bonds that hold the proteins and fats in solution. The soap's polar, or hydrophilic (water-loving), end dissolves in water, and its hydrophobic (water-fearing) end attaches to a fat globule in the milk. This is when the fun begins.
The molecules of fat bend, roll, twist, and contort in all directions as the soap molecules race around to join up with the fat molecules. During all of this fat molecule gymnastics, the food coloring molecules are bumped and shoved everywhere, providing an easy way to observe all the invisible activity. As the soap becomes evenly mixed with the milk, the action slows down and eventually stops.
Try adding another drop of soap to see if there's any more movement. If so, you discovered there are still more fat molecules that haven't found a partner at the big color dance. Add another drop of soap to start the process again

Why does food coloring spread when you put dish soap on the milk?
because soap break down fat in milk
Why does food coloring go in strings and not spread out?
The food coloring is more dense than the water.
What is the hypothesis of color changing?
A good experiment is to pour milk onto a plate and then apply drops of food coloring. Then dip a Qtip into some dish soap and apply it to the milk. The soap acts on the chemicals within the milk and allows the changes in the fat and protein molecules to be observed.
What does the dish washing soap have in it to help the food coloring burst?
it has a chemical that breaks the milk che mical to make the food coloring burst
Does dawn dish soap and food coloring for a chemical reaction?
well,it depends on what soap you use and its the chemical reaction in the soap that effects the food coloring and milk.
Why does food coloring spread in water?
because it is liquid mixing in to another liquid
How does liquid dish soap make food coloring in milk expand?
it make it expaned by thee ingredents in the dish soup and the surface tension and sulfur.
How do you detect flavonoids?
spread salt and food coloring around and have ure dog pee on it
How does the celery absorbs the food coloring?
The xylem tubes, tubes that suck up water and minerals in a plant, in the celery plant suck up the food coloring which to the tubes, is water. The tubes then just spread the water/food coloring to other parts of the celery.
What will happen to a drop of food coloring when added to a cup of heated water?
The food coloring will spread throughout the water and become homogeneous faster than it would in cold or warm water. The food coloring would also mix evenly with the water faster if you stirred the water after adding the food coloring. This happens because the molecules are moving faster when they are heated up stirred.
Is there DNA in food coloring?
no there is not DNA in food coloring
What makes food coloring stick to food?
food coloring doesnt stick to food it obsorbes into food
