Takeaways

• 😀 Dry ice is made from frozen carbon dioxide and has a temperature of -109.3°F (-78.5°C).
• 😀 Dry ice creates a spooky bubbling effect when added to warm water due to sublimation.
• 😀 It’s important to use warm water with dry ice to maximize the bubbling effect.
• 😀 Dry ice can be safely stored in coolers, but it should not be kept for long periods due to sublimation.
• 😀 Dry ice is often used in Halloween experiments and can be purchased from grocery stores, but getting it on Halloween day can be difficult.
• 😀 Adding soap to a graduated cylinder with dry ice creates a foamy, bubbling reaction that is fun for kids to watch.
• 😀 The foam created by dry ice and soap is safe to touch and continues to bubble as long as dry ice is present.
• 😀 When using dry ice in experiments, it’s safer to use containers like graduated cylinders, preventing kids from directly touching the dry ice.
• 😀 Dry ice can be added to apple juice to create a fizzy, bubbling effect, but it should not be served while bubbling.
• 😀 Once the dry ice in the apple juice has fully sublimated, the resulting drink is cool and refreshing.
• 😀 Using a cloth soaked in bubble solution with dry ice can produce magical crystal bubbles for a spooky Halloween effect.

Q & A

What is dry ice made of?

Dry ice is made of frozen carbon dioxide (CO2).

What is the temperature of dry ice?

Dry ice is extremely cold, with a temperature of -110°F (-78°C).

Why does dry ice make a screaming noise?

The 'screaming' noise is caused by the rapid sublimation of dry ice as it transitions from a solid to a gas.

Can dry ice be purchased from a grocery store?

Yes, dry ice can be found at some grocery stores, typically stored in a cooler to maintain its low temperature.

How should dry ice be stored to prevent it from disappearing quickly?

Dry ice should be stored in a cooler, and it is best to buy it the night before an event as it can sublimate quickly, especially on the day of the event.

What is the effect of adding dry ice to warm or cold water?

Adding dry ice to warm or cold water causes bubbling, with a spooky effect being enhanced by colder water.

What is the purpose of adding soap to dry ice in a cylinder?

Adding soap to dry ice in a cylinder creates continuous bubbles, which can entertain children, as the soap traps the carbon dioxide gas.

Why is it important to use graduated cylinders for experiments with dry ice?

Graduated cylinders are used because they prevent children from reaching into the container while still allowing them to observe the effects of the dry ice.

What happens when dry ice is added to apple juice?

When dry ice is added to apple juice, it causes the liquid to bubble, creating a fun and visually appealing effect.

What is a crystal bubble, and how is it made?

A crystal bubble is made by using a piece of cloth soaked in bubble solution, which is then pulled across a surface, trapping carbon dioxide and forming a bubble that can be visually striking.
