Pouring Liquid Nitrogen in a Pool - (I set my pool on fire!!)

The video explores experiments involving dry ice and liquid nitrogen to extinguish fires. Initially, a viral video idea is discussed, followed by a demonstration of using liquid nitrogen to put out flames, creating a cool visual effect. Observations are made using a thermal camera. The video then shifts to experimenting with dry ice in a pool, resulting in an underwater tornado effect. Finally, dry ice is used to extinguish a diethyl ether fire, highlighting safety precautions.

What is the main purpose of using liquid nitrogen in the experiment?

• To create a visual effect

• To cool down the environment

• To increase the temperature

• To displace oxygen and extinguish fire

What unexpected visual effect was observed during the liquid nitrogen experiment?

• A rainbow

• A tornado

• A lightning strike

• A fog

How does liquid nitrogen help in extinguishing fire?

• By forming a layer of nitrogen gas that blocks oxygen

• By absorbing heat

• By increasing humidity

• By creating a vacuum

What phenomenon was created by the dry ice in the pool?

• A wave

• A whirlpool

• A geyser

• An underwater tornado

What safety incident occurred during the dry ice experiment?

• The narrator's hand caught fire

• The pool overflowed
