My science helper, Brenna and I, are trying to make an experiment.
It?s one you are going to want to try at home
It?s called, The Milk Rainbow.
Notice my pan here and take a closer look.
We filled it with milk. You'll notice different blobs of food coloring.
Make sure you evenly spaced out the food coloring.
Another important ingredient is dish soap.
Go ahead and take that cotton swab and dip it into the dish soap.
Now, what I want you to do is to touch the surface of the milk with dish soap and let?s see what happens.
Look at that.
We have a rainbow of colors!
Pretty cool, Brenna.
Here?s what?s going on.
The milk contains water, protein and fats.
The surface has surface tension.
Here?s what the dish soap did. It interacts with the fat in the milk and reduces the surface tension creating a milk rainbow.
For Hooked on Science, I?m Jason Lindsey.
You might see a rainbow after a storm, but have you ever found one in your milk? Jason Lindsey, aka "Mr. Science," with Hooked on Science and a kid scientist show us the “Milk Rainbow.” Go to http://www.hookedonscience.org/nextgenerationsciencestandards.html for the FREE NGSS experiment guide.
