Milk food coloring and dish soap

On 'Renaissance,' Beyoncé Demands Joy

Milk, especially whole milk, contains fat and proteins. When soap is added to milk, the hydrophobic end of a soap molecule grabs onto a fat molecule in the milk. With millions of molecules finding a partner all at once, the mixture gets all stirred up! You will notice in my video that it looks like the milk is erupting for several seconds after dish soap is added. This is why. It truly is magic milk! Milk and dish soap experiment Detergents (including dish soap) are surfactants. These are things that break up the surface tension of liquids like water or milk. All surfactants are made up of molecules with two parts: a hydrophilic part that attracts water, and a hydrophobic part that repels water but interacts easily with other things, like fat molecules and the surface of casein micelles.

Drop just one drip of dish detergent in the middle of the milk. Watch what happens! The colors will sink in response to the dish detergent, then emerge again—marbleizing and combining—before stabilizing and standing still Please Leave a Comment: Cancel reply World's Biggest Milk Food Coloring And Dish Soap Experiment!!

Repeat the experiment using water (in place of milk). Will you get the same eruption of color? What kind of milk produces the best color swirls: skim milk, 1% milk, 2% milk or whole milk? Why? These questions are the basis of a great science fair project. Creating your very own magic milk experiment is as easy as comparing the effect that the dishwashing soap has on a number of different liquids. Do you see any pattern in your observations? Investigating Liquids: Color Changing Milk The soap molecules cause a chemical reaction that makes the colors mix together and moves around in the milk.

Build a snowman from the warmth of your home or classroom using fake snow. Then watch and hear the chemical reactions as you pour vinegar over your creation. Modify your experiment by incorporating dish soap into your snow and observe how the reaction changes.
