Art and Science Smash-Up: Milk Swirls Paintings

Milk Swirl Painting

milk and food coloring paintingI saw this idea on Photojojo a couple of days ago and immediately thought of doing this with Adia, who is very good at math and science. When I suggested this fun experiment for today, she was all over it! She remembered seeing the project on a website she called “Science Steve.”  Here is an excerpt from Steve’s post about this Color Changing Milk:

The secret of the bursting colors is the chemistry of that tiny drop of soap. Dish soap, because of its bipolar characteristics (nonpolar on one end and polar on the other), weakens the chemical bonds that hold the proteins and fats in solution. 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.

Milk Swirl Painting in ProgressSteve’s description of this experiment explains that it’s important not to stir the colors and the milk with the cotton swabs, but Adia couldn’t stop herself. She seemed much more interested in seeing what would happen when you stir all the colors together (you get a grayish tan color that looks totally unappetizing!)

I convinced Adia to let me to take photos along the way, before the colors were all mashed together. Aren’t these cool? The blue one looks a little like an angry face.

What You Will Need

  • Whole or 2% milk (must have some fat for the science to work)
  • Dinner Plate
  • Food coloring (red, blue, green, yellow. We also used Neon colors)
  • Dish-washing soap (We used Ivory Liquid, but some sites say Dawn works best)
  • Q-tips (cotton swabs)

How to Make your Milk Swirl Paintings

Pouring milk for milk swirl painting
Pour a thin layer of milk onto a dinner plate that has a lip (we had to level our plate with a shim under one side

 

Beginning of Milk Swirl Painting
Put a few drops of food coloring into the milk
Green and Yellow Milk Swirl Painting
Touch the soapy swab to the colors in the milk and watch what happens.

The color zooms away from the swab tip and makes beautiful, interesting shapes. You can keep dabbing the swab onto the colors, add more drops of color if you want.

You can also drag the swab lightly through the colors to make swirls and shapes.

Take photos! These make really cool abstract designs

Homestyle Art Fun: Ink Painted Tiles

Well, today was Jaime’s first day at her new job — and my first full day with Ema and Adia. And whoah! did we ever pack alot of fun stuff into one day! We started out by choosing a couple of projects from our Summer Fun Pinterest board, then running around town for an hour or so gathering supplies.

Our first project was to make ink painted tiles inspired by this link … we had to do a little googling to figure out exactly how to do it and which supplies we needed, plus we added our own spin (Adia named our technique “Straw-mania.”) I will let Adia and Ema write a blog post later this week with details on how they made their tiles.

SummerFunMonday01-imp Paint Sample Memory GameWhile we waited for our tiles to dry, we made smoothies (strawberry-peach-banana-amond) and sandwiches and ate lunch while playing “Memory.” We made our own Memory game with paint samples. That was a hit. I think we’ll keep the deck for other days. Then we walked down to Johns’ house to play with Tuffy for a few minutes, water Jaime’s garden a little and, oh yeah — get the marshmallows for the Rice Krispie Treats.

After lunch, we made krispie treats, then snuggled on the sofa and watched “The Lorax” on our Netflix instant-play. Sun tea and krispie treats during the movie… the girls had never made krispie treats. They got to do the whole thing themselves. (Confession: we ate almost half the pan — big grin)

We filled the rest of the afternoon with quiet activities: I taught them to make a campfire in the back yard, and the girls showed me how to make friendship bracelets . I am now wearing the one Ema made for me and she is wearing mine. I have a prediction: we’ll be making lots of friendship bracelets this summer. It’s easy, cheap, and something you can do for an hour while you are waiting for your mom to come home from work. 🙂 Besides I need to make one for Adia!

Tomorrow: make Charlie’s dog food. Get goldfish for the pond. Take Charlie out to play along the irrigation canal … make some silly videos and check out the classic cars at the Montana Dept. of Transportation 100th Birthday Celebration. Another non-boring day. 😉

I am having a glass of wine with my dinner tonight…
