Whoa! Today Ruma Whitu observed a new science experiment this week! Check out our photos below.
All you need for this experiment is room temperature milk, dish washing liquid, food colouring, and a bowl.
When you add in the dish washing liquid, the colours in the milk start moving around the bowl really fast. Campbell said, "it looked like a tornado." All the colours mixed together.
What is the science behind this experiment?
Why did the colours mix together and move so fast?
This activity teaches the concept of chaos.
The dish washing liquid has two different ends. One end likes water and one end likes fat. The dish washing liquid moves through the milk with one end looking for fat and the other looking for water. On their chase through the milk the dish washing liquid molecules stir up the food colouring and that is why you see the colours mixing and moving together.
Ooh,I might try that experiment tomorrow too.
ReplyDeleteYes. This one is my favourite! The magic milk experiment. We are going to do it again in groups.
