RAINBOW MILK EXPERIMENT
In a pandemic situation like now, sometimes we all feel bored with having to do all the activities in the house. And sometimes, we are also confused about what we will do in the house.
But, I have the answer ! Yes, the answer is to do experiments. Doing experiments can solve your boredom at home and increase your knowledge. So, I'm going to invite all of you to do a little experiment, namely "Rainbow Milk Experiment".
Goals :
Have you even see rainbow before? If you have, I bet it was in the sky. Did you know that you can make your own rainbow with some milk and a few other materials? Did you know that it is easy to turn ordinary milk into a rainbow of crazy colors? Isn't it very interesting, right? It is fun to be able to make a rainbow on the milk. So far we know that rainbows are a creation of God in the sky, but we can also make our own rainbows on milk, but how?
To answer your curiosity, let's go to follow my instructions below this ! If you want more details, you can see the video above! Don't forget to wear a lab coat!
Materials :
- A whole white milk
- Liquid dish soap
- A bowl
- Cotton swabs
- 2 or more different colors of food coloring
Steps :
1. First, gather your materials.
2. Next, pour your milk into the bowl until it is about on inch deep.
3. Then, wait until there are no bubbles and the milk is still.
4. After the milk has no more bubbles, put a few drops of each color of food coloring into separate places inside the milk.
5. Next, take some liquid dish soap.
6. After that, dip a cotton swab in the dish soap.
7. Next, take the bowl filled with milk that has been dropped with food coloring.
8. And last, place a cotton swab dipped in dish soap on the surface of one of the colors in the milk, and see what happens.
9. Finally, we've finished making a rainbow milk.
Science Explanation :
When dish soap is dropped into milk, there is a swirl of activity of soap molecules finding and bonding with fat molecules in the milk. With millions of molecules swirling around looking for mates, the colors in the milk get all mixed up. It looks like the milk is erupting for several seconds.
Milk is made up of mostly water, but it does contain vitamins, minerals, proteins, and small droplets of fat. The fat and proteins are super sensitive to changes in the milk and so when the dish washing liquid is added, a chemical reaction occurs.
The soap and fat work hard to join together, which causes the movement. As the majority of soap molecules attach to the fat molecules and the soap spreads throughout the milk, the color explosion will slow, slow, and eventually stop.
*WARNING
THIS RAINBOW MILK SHOULD NOT BE DRUNK!
BECAUSE THERE IS ALREADY A CHEMICAL REACTION TAKING PLACE IN IT!
