When you first put the detergent on the milk,
the negative end of the detergent molecules line up with the positive end of the water molecules
. This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring out toward the edge of the plate.
What happens when you put dish soap in food coloring?
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.
How does milk and food coloring react to soap?
When liquid dish soap is added to milk with drops of food coloring on the surface,
the soap reduces the surface tension of the milk and reacts with the fat
. This interaction causes the fat particles in the milk to move and create swirls of color.
What happens when you add soap to milk?
The fat-like end of the soap molecules join with the fat in the milk and as
the soap spreads across the surface of the milk
, more and more fat molecules are pulled by the spreading soap. When the fat molecules congregate, the polar water in the milk is pushed away, taking the food colouring with it.

What causes food coloring to spread in milk?
The milk is made mostly of
water molecules
, but it also has fat molecules and protein molecules which are bigger than water molecules. … This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring out toward the edge of the plate.
What happens when you place the first drops of food coloring on the milk surface?
When droplets of food coloring are placed onto the milk’s surface,
the food coloring stays suspended on the surface in a small area
. When you touch a cotton swab soaked in soap to the milk, the colors spread throughout the milk creating colorful swirls.
How does the soap work?
“Pin-shaped soap molecules have one end that bonds with water (the hydrophilic head) and the other end that bonds with oils and fats (the hydrophobic tail). When you build up a soapy lather,
the molecules help lift the dirt, oil and germs from your skin
. Then, rinsing with clean water washes it all away.”
What happened to the food coloring in the hot water?
In hot water, the
food coloring diffuses (spreads out) through the water quickly
. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster.
Why does dish soap not mix with milk?
Milk
contains fat
. Dish washing soap bonds to fat. So the molecules in the soap are racing around joining up with fat molecules. It keeps going until the soap becomes evenly mixed in the milk.
Is adding food coloring to milk a chemical change?
Milk is made up of mostly water but it does contain vitamins, minerals, proteins and small droplets of fat. … The soap and fat work hard to join together, which causes the movement. When food colouring is added we are able to

this chemical reaction occurring.
