The candle can’t be blown away:
Blowing the burning candle, but how can it not blow. Do you know how to do this?
Materials: 1 candle, match, 1 small funnel, 1 flat plate operation: 1. Light the candle and fix it on the flat plate.
2. With the wide mouth of the funnel facing the flame of the candle, blow it against the flame from the small opening of the funnel.
3. Make the small opening of the funnel facing the flame of the candle and blow it against the flame from the wide mouth of the funnel.
Explain: 1. When blowing, the flame will be inclined to the wide end of the funnel and will not be easily blown out. If you blow from the wide mouth of the funnel, the candle will be easily extinguished.
2. When the blown gas is from the fine mouth to the wide mouth, it gradually dissipates and the air pressure is weakened. At this time, the gas around the wide mouth of the funnel will flow into the wide mouth of the funnel due to the strong air pressure. Therefore, the flame of the candle will also flow to the wide mouth of the funnel. The first model network to organize the article, the copyright belongs to the original author, the original source.
Note: Pay attention to the safety of the candle burning
