Because I love coffee, I ended up drinking the national science exhibition champion.
Luo Yilin, a sophomore in Taiwan, drank many brands and countless fresh milk for a year and found that the addition of 1.5 centimeters of coffee to the foam could reduce the shock amplitude by 57%, that is, the damping effect of the foam on the liquid. Verify the physical fluid mechanics, won this year's National Science Exhibition Agriculture and Food Champion and Best creativity Award.
What is the damping effect?
The damping effect comes from the friction between the milk foam and the cup wall, the greater the friction, the less spatter. From the little things in life to do research to verify the theory of fluid mechanics, from being judged and doubted to being favored, it is not easy to get the first place.
From being doubted by the judges to being favored, it is not easy to get the first place.
The damping effect is different due to the oil content and sugar content of fresh milk, and the damping effect of high fat content and dense fructose is more obvious, so many experiments are needed.
The most difficult part of the research process was that there was no vibrator to do the experiment. later, they drew designs, which were made by DIY Chen, a teacher who knew how to do carpentry, which could shake the milk foam vertically and horizontally.
