What is dry ice?

Dry ice is a solid substance made up of carbon dioxide (CO2). This name is due to its appearance to ice and its solid, but it does not keep any moisture around it. Another interesting feature of this substance is that, at a given temperature, rather than melting, it is also converted to gas. This process creates white smoke that is used as a fog or smoke effect in filmmaking. This smoke actually brings the humidity of the environment in a way that turns into water vapor.

Dry ice is also used as a cooling material. It is converted from solid to solid by combining CO2 gas at a fixed temperature of about -78.5 degrees Celsius (-109.2 ° F). In fact, the energy needed to change the phase from solid to gas (outeri -condensate) at 78.5 ° C is 199 kg / kg.

The use of dry ice in various cases, including an artificial smoke source for filmmaking, is very common in some processes as well as in experiments and research.

How to make dry ice at home

Dry ice is one of the interesting and attractive experiences that you can easily get home. This process not only gives you a new way of entertainment, but can also use dry ice as a tool in producing artificial smoke, preparing carbonated drinks, maintaining food and even preventing pests.

Follow the steps below to make dry ice at home:

How to make dry ice at home

Making dry ice at home in a simple way

1. Making dry ice with compact CO2

Use a CO2 firefighting capsule and a cloth pillow to make dry ice at home. The CO2 firefighting capsule must have a plastic branch. This method can quickly produce dry ice.

2. Protect your hands, eyes and organs

Before starting the process, make sure you use thick leather gloves, laboratory glasses, long sleeves and trousers, closed front shoes. Dry ice is very cold and take safety to protect your skin and eyes.

Methods

3. Wrap the rowing tightly around the hose

Stick the plastic branch of the fire extinguisher capsule and press the routine handle upwards. The pillow must be sturdy and without a hole to transfer the CO2 gas into the pillow.

4. Open the fire extinguisher capsule

By pressing the base handle, the extinguisher will be compressed inside the capsule and the CO2 gas will be out of the pillow. There is a mass of dry ice there. Release the handle after a few seconds.

5. Remove the pillow

Remove the pillow carefully from the branch and wipe the dry ice cloth with a cloth. Note that dry ice is very cold and you should prevent direct contact with the skin.

The second way to make dry ice

The second way to make dry ice is to provide a carbon dioxide capsule (at least 75 times and a temperature of about 31 ° C). Then invent the capsule to place the outlet valve at the bottom and open the valve. In this case, CO2 is removed from the capsule as dry ice. This phenomenon is caused by the process of oppression or suffocation that results in the sudden evaporation of CO2 gas and the formation of dry ice.

These descriptions will help you make dry ice at home quickly and safely. Be sure to consider the recommended precautions and safety measures to prevent any problems.

Applications of dry ice

Dry ice, in addition to being an attractive home experience, has many uses in everyday life. These applications include:

1- To produce fog-like gas, combine dry ice with water. One of the common uses of dry ice is the creation of synthetic fog or fog. This is simply done by mixing dry ice and water. By splashing water on the ice, the sound will be scratched and a lot of carbon dioxide will produce.

Different applications of dry ice at home

This is useful in dances, rock concerts, scary homes, and other places that require a mysterious space. Keep in mind that carbon dioxide production only in open ventilation. However, it is low, creating a large amount of carbon dioxide in the environment with poor ventilation can reduce oxygen and make breathing difficult. If you use a small hole container, you can act like creating a foggy sprinkle. This may even be more advanced and can move a small engine or rotate the wheels.

2. Use dry ice to create carbonated drinks. Another use of dry ice is the production of carbonated beverages such as beverages, beer, champagne and carbonated water. By placing dry ice in the water, carbon dioxide is released in the water and thus accumulates in small cups for carbonated drinks. Although many commercial manufacturers as well as home beverages use liquid CO2 (instead of dry ice), it still has an impact on dry ice. Wait for a complete dry ice before you drink; Because swallowing dry ice can damage the internal tissues. Also, some people may not like the taste of dry ice in carbonated drinks, so it is best to test with a small amount before adding to the main drink.

How to use dry ice

Use dry ice to store food. Dry ice is much colder than ordinary ice and can keep foods and drinks colder. But be careful not to get cold enough to break down; For example, placing a champagne glass on dry ice can cause it to break or even freeze. Therefore, use dry ice only for foods and drinks that are more cold. Also, if you want to use dry ice in the fridge, put it in the ice and then close the refrigerator door; This helps to keep dry ice.

Applications of dry ice

4- Use dry ice to store soft and loose food. Surprisingly, you can use dry ice to keep fresh materials such as cereals, beans, lentils and pasta. To do this, first place the dry ice on the bottom of a ice chest, then place your food on it. After that, place the dry ice on the ingredients and gently close the ice lid. This will create a colder and usually frozen environment for your material. Due to the dry ice sublimation, carbon dioxide is released, which is heavier than the air and expels the air inside the chest. This will make germs less access to food and extend their useful life.

5. Use dry ice to collect solids. As mentioned earlier, dry ice is cold enough to make materials such as metal and ceramics smaller and more accurately. This feature can be used in certain cases.

For example:

In removing the troughs of the car, you can remove small metal dings with a dry ice block and a heavy glove using dry ice.

To remove the floor tiles, you can put dry ice on the tile and wait for the tile to cool and have a collected base.

6. Use dry ice to control pests in the yard. Since carbon dioxide is heavier than air, dry ice can be used to control pests such as moles and gofters. To do this, place small pieces of dry ice in holes or pests and then cover the holes with soil. When the dry ice is submitted, carbon dioxide is released, which is heavier than the air and kills pests.

The risks of dry ice

Dry ice can also be dangerous because it is really cold! Long -term exposure to dry ice causes your skin cells to freeze and get some kind of burns. In the meantime, if you throw it into your drinks, be careful not to swallow it.

In addition, you must excrete dry ice in a proper manner; Do not pour it into the dishwasher and do not throw it into the trash. You can pour hot water into the dried ice container to speed up the dry ice sublimation process.

In addition, be sure to use dry ice in a room that is well ventilated because high breathing is especially fatal for children. Finally, if you put the dry ice in the container completely in the closed or in the freezer, it will put pressure on it and explode. So be careful not to make a dry ice bomb!

Safety tips to use dry ice

Prevent direct skin contact with dry ice as it can cause frostb burial. When touching it, be sure to use insulation gloves.

Keep dry ice in ventilation places because it has a large amount of carbon dioxide, which increases its concentration in the blood. Avoid keeping dry ice in the refrigerator, freezer or other place where there is no air conditioning, as it increases pressure and ultimately unintended explosive consequences.

If you carry dry ice in the car, be sure to use ventilable containers to keep it and lower the car glass to prevent gas.

It is difficult to cut and crush dry ice. So try to buy it in the shape and size you need. If you want to cut it, be sure to use insulation gloves and protective glasses.

Allow the remaining dry ice to be converted into a gas in an area with proper ventilation. This should only be done outdoors. Just make sure you keep it away from children and pets.

Never eat dry ice and don't swallow.
