Looking for simple examples of breaking feudal superstition with chemical experiments

Chemical experiments can reveal the essence and changing law of matter, while feudal superstition is a belief or concept without scientific basis. The following are some simple examples of debunking feudal superstitions with chemical experiments:

1. Silver needle poisoning test

In feudal times, people often tried poison with silver needles, thinking that the blackening of silver needles meant toxic substances. But modern science has proved that silver will not react with daily food or medicine, so this method is not reliable.

Burning water

Some charlatans will use some mysterious spells and potions, claiming that they can cure various diseases. However, chemical experiments can prove that these spells and potions have no scientific basis and may cause harm to human body.

tell sb's fortune

Some people believe that fortune telling can predict the future, but chemical experiments cannot prove the accuracy of this belief. On the contrary, scientific research shows that people's decision-making and behavior are influenced by many factors, including environment, psychological state, physiological state and so on. Therefore, the future is unpredictable, so we should believe in scientific and rational thinking.

In a word, chemical experiment is one of the important means of scientific research and development, which can help us reveal many natural phenomena and changing laws. Feudal superstition is a belief or concept without scientific basis. We should keep rational thinking and scientific attitude, and don't easily believe statements or practices without scientific basis.
