5 weird ways to put out a candle

The video explores five unconventional methods to extinguish a candle. It begins with using a copper coil to remove heat and oxygen, followed by demonstrating airflow dynamics with rounded objects. The video then shows how carbon dioxide from dry ice and a baking soda-vinegar reaction can put out a flame. Finally, it features an experiment with liquid nitrogen, highlighting its cooling effect and density. Each method is explained with scientific principles, emphasizing heat, oxygen, and airflow's roles in sustaining a flame.

What role does the copper coil play in extinguishing the candle flame?

• It provides fuel for the flame.

• It increases the temperature of the flame.

• It removes heat and limits oxygen.

• It adds more oxygen to the flame.

Why does a rounded object help extinguish a candle flame?

• It increases the temperature around the flame.

• It allows air to flow smoothly and hit the flame.

• It blocks all airflow to the flame.

• It reflects light away from the flame.

How does placing a glass over a candle extinguish the flame?

• By increasing the temperature inside the glass.

• By allowing more oxygen to enter.

• By limiting the oxygen flow and circulation.

• By reflecting light onto the flame.

What is the primary reason a candle goes out when covered with a glass?

• The glass reflects light onto the flame.

• The glass limits oxygen and airflow.

• The glass allows more oxygen to enter.

• The glass increases the flame's temperature.

What happens when dry ice is used to extinguish a candle?

• It increases the flame's temperature.

• It releases carbon dioxide, which is denser than air.

• It cools the flame with water vapor.

• It adds oxygen to the flame.

What is the result of using baking soda and vinegar to extinguish a candle?

• It produces carbon dioxide to suffocate the flame.

• It creates a vacuum around the flame.

• It adds more fuel to the flame.

• It increases the flame's brightness.

How does liquid nitrogen extinguish a candle flame?

• By adding more oxygen to the flame.

• By cooling the flame with cold nitrogen gas.

• By increasing the flame's temperature.

• By reflecting light away from the flame.
