Hi
i show how to create the dry ice with a fire extinguisher (CO2)

BE CAREFUL FOR THIS PROJECT , BECAUSE THE CO2 CAN CREATE BURNS

Step 1: You Need...

For this project you need:
-Fire extinguisher (ONLY CO2 BE CAREFUL)
-Pillowcase
-snow gloves

Step 2: Start

the first thing to do remove the security of the fire extinguisher

Step 3: The Pillowcase

put on your snow glove.
grab the pillowcase and put in the mouth of the extinguisher

Step 4: Be Careful

in this step you must be very careful..

when your pillowcase is on fire extinguisher pull the lever until the fire extinguisher is emptied...
now the Co2 solidified in the pillowcase

Step 5: Finish

collect your dry ice in a metal bowl, unfortunately, you can not preserve...because it will melt very quickly...

then use for your experiments, before it melt

thank you for your attention
