Dry Ice Experiments and Safety

The video tutorial demonstrates various experiments using dry ice, including carbonating apple juice, creating soap bubbles, and using lighting effects to make bubbles glow. Safety tips for handling dry ice are provided, and the video concludes with information on where to find more resources.

What is a key precaution to take when handling dry ice?

• Use a cooler for transport

• Touch it with bare hands

• Store it in a refrigerator

• Leave it in the sun

Why should you avoid storing dry ice in a refrigerator?

• It will become wet

• It will lose its coldness

• It can cause the refrigerator to shut down

• It will melt quickly

What happens when dry ice is added to apple juice?

• It changes the color of the juice

• It freezes the juice

• It carbonates the juice

• It makes the juice taste sour

What is the purpose of using soap solution in the dry ice experiment?

• To change the color of the bubbles

• To clean the dry ice

• To create bubbles

• To dissolve the dry ice

How do you trap carbon dioxide inside a bubble using dry ice?

• By freezing the bubble

• By heating the bubble

• By using a vacuum

• By pulling a soap-covered string across the bowl

What happens to the bubbles as they get heavier?

• They float higher

• They change color

• They pop and release carbon dioxide

• They become solid

Why is it important to experiment with different bowls in the bubble experiment?

• To test the durability of the bowls

• To find the right size for the bubbles

• To see which bowl holds the most water

• To determine which bowl creates the best bubbles

What effect does dimming the lights have on the bubble experiment?

• It makes the bubbles disappear

• It enhances the glow of the bubbles

• It causes the bubbles to pop

• It changes the color of the bubbles

How much dry ice is recommended for these experiments?

• 10 to 15 lbs

• 20 to 25 lbs

• 1 to 2 lbs

• 5 to 10 lbs

What is the approximate cost of dry ice per pound?

• $0.50

• $1.00

• $1.50

• $2.00
