What are some small experiments with red scarves?

Red Scarf’s small experiments include the experiment of how much water determines the pitch of the sound, the experiment of extinguishing the candle, and the experiment of not falling the table tennis ball. The relevant information is as follows:

1. The amount of water determines the pitch of the sound. Experiment: Pour unequal amounts of water into two cups, tap the cups with chopsticks, and observe the sound the cups make. This experiment can understand the relationship between the frequency of sound and the amount of water.

2. Candle extinguished experiment: light a candle and place it at the bottom of a transparent glass. After a period of time, place the glass upside down on the candle and observe the phenomenon of the candle extinguishing. This experiment can help you understand the principle of oxygen and air required for combustion.

3. Experiment on not dropping the table tennis ball: Place the table tennis ball at the bottom of the cup, put the straw close to the table tennis ball, and blow the straw out of the cup while blowing. At this time, you find that although you have been blowing, the table tennis ball is not falling. But he kept following the straw and wouldn't fall. This experiment can help you understand the relationship between fluid flow velocity and pressure.
