MILK EXPERIMENTS AND MILK DRAWING

avatar

As a rule, people buy milk for food or cooking, but I bought it for...our unschooling experiments and creativity!

We need just:

  • milk
  • some dyes

  • some stones or plasticine objects, glitters etc

  • cotton
  • soap

It will be our first experiment that will show us a cool reaction between soap, dyes and milk.

🎇WHAT TO DO:
Pour milk into a plate and decorate it with any suitable materials. Add a few drops of multi-colored dyes to different parts of the milk.
We tear the cotton pads into pieces, roll them into lumps, put them in a glass and soak them with liquid soap.


Now you can dip the soaked cotton balls into milk and enjoy the amazing movement of dyes mixing with each other in various patterns, similar to space galaxies!

🎇Explanation:
Milk contains fat which is involved in the formation of a film on the surface of milk, when the molecules are more strongly attracted to each other on the surface, and not inside. Scientifically, this phenomenon is called "surface tension".
When we add liquid soap to milk, it begins to interact with the fat of the milk and breaks the surface tension. Thus, the soap "breaks" the film into small pieces and creates small waves and rings on the surface of the milk, which carry along the dyes, forming beautiful patterns and swirls.

The effect is really charming! It looks super nice!✨

And we so liked this milk experiment that we decided to make one more...btw, we had some dyes left so it was a good idea to use them again.

We need:

  • milk
  • plant oil (2 spoons)
  • dyes

🎆WHAT TO DO:

Pour some milk into the saucer so that it completely covers the bottom. Add a thin layer of sunflower oil on top.
We dilute several colors of dyes in small cups. We take a pipette and with the help of drops we create any pictures we like! Then we will get small separate drops.

To create a beautiful background, squeeze a large drop into an empty space on the plate. When it becomes too heavy, it will sink down, mix with milk and color it.

🔻Explanation:
This colorful experiment is obtained due to the fact that water and oil do not mix, and also have different densities. The bonds between water and oil molecules are completely different, so liquids remain separate layers.
Water and dyes diluted in it have a greater density than oil and, accordingly, a greater weight. Therefore, large drops of dyes in the oil gradually sink down to its border with water. And when they overcome it, they mix with milk and color it. However, oil can hold small colored drops of water on its surface.

Milk pictures were so fantastic and unusual for us that we spent about an hour playing this game, and my son was in love with it, though he isn't a great painting lover.

Guys, have you ever tried such kind of drawing?

Wow, I never thought milk could be used as an art. Your idea is impressive.

I really like the first one. The colors are so beautiful in the end. We tried something similar with the second experiment, and added the soap too. I think you shared this one too?
Anyways, it looks fun all your experiments and I'm sure your boy is having a good time learning like this.
#learningthroughplay is what I'm trying always with Caleb.
