Dry Ice Safety and Usage

Colin Kilbane demonstrates how to create an indoor smoke bomb using dry ice and hot water. He emphasizes safety precautions, particularly the dangers of sealing containers with dry ice, which can lead to explosions. The smoke produced is actually CO2 clouds, which are heavier than air and won't trigger smoke detectors. The video provides a step-by-step guide while highlighting the importance of safety measures to prevent injuries.

What is the main component used in the indoor smoke bomb that does not trigger smoke detectors?

• Liquid nitrogen

• Dry ice

• Baking soda

• Vinegar

What is the temperature of dry ice?

• 32° Fahrenheit

• 0° Celsius

• 110° below zero

• 100° Celsius

Why is it important to handle dry ice with care?

• It can cause burns.

• It can cause frostbite.

• It can cause sunburn.

• It can cause dehydration.

What should you never do when using dry ice in a container?

• Use a glass container.

• Use a metal container.

• Seal the container tightly.

• Leave the container open.

What is the primary reason the clouds from the smoke bomb do not set off smoke detectors?

• They are made of nitrogen.

• They are made of CO2.

• They are made of water vapor.

• They are made of oxygen.

What should you do first when making the smoke bomb?

• Shake the container.

• Add dry ice to the container.

• Pour hot water into the container.

• Seal the container.

What happens to carbon dioxide as it changes from solid to gas in the smoke bomb?

• It evaporates.

• It contracts.

• It remains the same.

• It expands.

What is the purpose of the safety release valve in the demonstration?

• To add more dry ice.

• To release excess pressure.

• To change the color of the smoke.

• To cool down the container.

What is the risk of sealing a container with dry ice inside?

• The container will melt.

• The container will shrink.

• The container will explode.

• The container will rust.

What is a potential consequence of a plastic bottle exploding due to dry ice?

• It will create a loud noise.

• It will release a pleasant smell.

• It can cut through skin.

• It will change color.
