1. There is a company that produces toothpaste in the United States. The product is excellent and the packaging is exquisite. It is deeply loved by consumers. Its annual turnover is booming, but it has stagnated after entering the eleventh year. The board of directors held a national manager meeting. During a high-level meeting, a young manager suggested expanding the existing toothpaste opening by 1mm. This decision increased the company's turnover by 32% in its fourteenth year.
2. In the 1860s, the typewriters produced by Shores Company had a slow rebound speed after being struck. Once the typist typed too fast, the keys would easily twist.
To solve this problem, one engineer suggested slowing down typing speed and placing commonly used letters under the clumsiest fingers, and less commonly used letters under the most nimble fingers. This is how today's keyboards are designed.
3. Hang a string on the ice cube, and then lightly sprinkle with salt. After a while, the ice and the string will stick together. Wear it around your neck and it turns into a crystal ice necklace.
4. In 1963, Mpemba added sugar to hot milk to make ice cream. If he had to wait for the hot milk to cool before putting it in the refrigerator, other students might occupy the refrigerator, so he put the hot milk into the refrigerator. What’s surprising is that Mpemba’s hot milk freezes much faster than other students’ cold milk.
5. In a certain city in the north, an aquarium opened. The 50 yuan ticket made it prohibitive for those who wanted to visit. The aquarium has been open for one year, and it is almost empty.
In the end, investors who were eager to use their money sold the aquarium at a "reduce price" and returned to the south in tears. After the new owner took over the aquarium, he placed advertisements on television and newspapers, soliciting ideas that could bring the aquarium back to life.
One day, a female teacher came to the aquarium and told the manager that she could make the aquarium's business better. Following her approach, a month later, the aquarium was packed with visitors every day, one-third of whom were children, and two-thirds were parents with children. Three months later, the loss-making aquarium began to make a profit.
