Dry Ice Cloud

Have you ever wanted to create your own cloud? According to Jason Lindsey with Hooked on Science you can and all you need is dry ice and a few other supplies from around the house.

Supplies

Pan

Water

Dry Ice

Bowl

Instructions

STEP 1: Fill the pan half of the way with water.

STEP 2: Place thermal gloves on your hands. Using a hammer crush the dry ice into pieces. Place the pieces of dry ice into a bowl.

STEP 3: Place the pan on the stove and bring the water to a boil.

STEP 4: Using thermal gloves remove the pan of water from the stove. Place the pan of water on a heat resist surface.

STEP 5: Using thermal gloves, from a distance above the pan of hot water, quickly pour the dry ice into the pan of hot water.

Explanation

When you placed the dry ice into the warm water a cloud formed above the bowl. Dry ice is frozen carbon dioxide and is minus-109.3 degrees Fahrenheit. As dry ice breaks down it turns directly into carbon dioxide gas. In science this process is called sublimation.
