Milk & Soap Science Experiment

Our children LOVE experiment days! This experiment was taken from Steve Spangler’s book: Naked Eggs and Flying Potatoes

First, the ingredients: we needed Milk, Q-tips, dish soap, and food coloring and a dish to pour it in.

  • Pour about 1/4″ of milk in your dish and let it sit till no bubbles.
  • Dot a drop of each color of food color in the center of the milk plate.

  • Place a Q-tip in the middle of all the colors, don’t stir, just stick in and hold. Anything happen?

Now, DON’T BLINK!, dip the other end of your q-tip in dish soap and get ready to see the soap and the fat in the milk dance! This experiment could be taken farther by doing it with different milks,… whole, 2%, skim, almond, etc…  We get to see the soap attacking the fat in the milk because of the food colors and even though we saw the pictures in the book, we we’re so excited about what happened!

Don’t stir the soap dipped q-tip, just stick it straight in and watch.

POW!

It changes too, as it spreads through the milk and finds new fat cells to disrupt. We re-soaked and re-dipped more q-tips in other areas to watch it change more.

We then started going out on our own wonderings… what happens if we drop vinegar in? (not much) What about water drops? ~ those were kinda cool, they seemed to make everything move under the surface to make the top make this happen:

It left those circular “openings” in the color, and even made patches of color circles pop up in a different color section!

We let it sit for a couple of minutes, and I guess the soap and the couple of drops of vinegar that we put in it gave it a different density, this next picture is of water drops from a medicine dropper… it looks like it is probably a bit solid because those “holes” stayed, but it wasn’t, it poured smoothly down the drain. So interesting! (yea, that’s the nerds in all of us)

Try it for yourselves and let me know what you think!

Have a Blessed Day!
