Little Explorers: Milk Magic

A couple of friends have recently asked if I have any good science experiments they could do with their kids with basic household stuff.  Ummm...YES!  Of course!  I'll attempt to gradually post my favorites as I do them with Isabella and Oliver.  If you try it out let me know how it goes and if you want me to post more.  I'd love your feedback!

Milk Magic

Here's what you need:
  • whole milk
  • food coloring
  • liquid dish soap
  • q-tips
  • pie plate
Pour the milk into the pie plate just enough to completely cover the bottom.  Let it settle for a minute.  Put a drop (or two) of each color of food coloring into the milk, near the center (but not on top of each other).  Dip the end of your q-tip into the liquid dish soap and put that right into the center of the milk.  Hold it there and watch the magic.  Younger kids will want to stir it, but encourage them to just hold the q-tip in one place.  Or pick up the q-tip and place it in another part of the plate to see what happens.

What is happening:

The fat and protein molecules in the milk are very sensitive to change.  When you add the soap to the milk the molecules go crazy and move around.  By adding the food coloring we can actually see how these fats and proteins act when combined with soap.

Extreme experimentation:

What happens if you try it in water or low-fat milk?

P.S. If any of you locals are ever interested in fun liquid nitrogen experiments (ice cream, perhaps?) let me know.  I can totally hook you up!

Attitude of Gratitude

I am grateful for a small home.  Some of the benefits of our little apartment:

  • it is easier and quicker to clean
  • we purchase and consume less stuff
  • we frequently clean out and purge the stuff we do have
  • we are always together as a family
  • I can keep close tabs on my little ones (usually :))
  • I use my awesome tetris skills when storing stuff in closets and cupboards
  • it encourages us to get out of the house and experience new, exciting things
I love the random photos my kids take.  They are like little prizes in a cereal box.
