I wanted to make the BIGGEST and LONGEST Milk Food Coloring and Dish Soap experiment ever! I wonder if I could have the record in the Guiness Book of World Records for this!!! This experiment took a long time to film and even longer to edit but it was all worth it!
I used milk that was passed its expiration that was going to be thrown out so no good milk went to waste!
You can easily make this cool Milk and Food Coloring science experiment at home! What you need:
cotton swab (q tip)
Just place some drops of food coloring as shown in the video over the milk (regular whole milk works best) and dip the q tip into some dish soap. Place the q tip with the drop of soap directly onto the food coloring and watch the colorful fireworks!
Why it Works: Milk is mostly water, but it also has tiny droplets of fat in it...Dish soap, ( I used Dawn Dish Soap but any will work) makes the chemical bond that hold the fat together in the milk. 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. You'll be surprised to see what happens. Add another drop of soap to start the process again.
