Liquid nitrogen is cold enough to exist in its liquid form.It is extremely cold and can be used for freezing.It is possible to make a poor man's liquid nitrogen out of regularly available items.It is a bit slower and needs to be handled with care.All health and safety precautions should be taken when working with dry ice and liquid nitrogen.
Step 1: You should gather your materials.
The substitute is made by combining dry ice and alcohol.99% isopropyl alcohol or rubbing alcohol will be used for our purposes.You will need a plastic bottle, dry ice, and scissors.A block of dry ice is hard to use.When in contact with the dry ice, isopropyl with an alcohol content of less than 99% will form a gel that won't work for this experiment.Styrofoam can be used if you don't have plastic containers on hand.Supercool temperatures can cause glass to break, so don't use glass materials.It's not a good idea to use metal with the very cold temperatures.
Step 2: To make a container, place the smaller bottle in the larger bottle.
You will place the smaller bottle inside the larger bottle to make an outer layer for the dry ice.The larger bottle that holds liquid with no leaks should be used for dry ice and the smaller bottle for liquid.Start by removing the tops from the bottles.Carefully poke the small holes in the bottle.Make holes large enough for the alcohol to flow out, but small enough that dry ice can't get through.The smaller bottle should be in the middle of the larger bottle.
Step 3: Get rid of the dry ice.
You need pieces that are small enough to fit in the space between the large and small bottle.To fill the space, crush as many pieces as you can.If handled for too long, dry ice can burn you.To prevent injury, use an oven mitt or other protective glove.Put your block in the sink if you didn't get the pellets.Put the board and block of dry ice in a large bag.Cut the block with a knife or hammer.
Step 4: Dry ice is used to fill the outer space.
The space between the bottles should be filled with small pieces of dry ice or block.To get to the top, fill the space halfway.Don't put dry ice in a bottle.The dry ice should be below the bottle.
Step 5: Rub alcohol on the ice.
Slowly pour the alcohol around the outside of the smaller bottle.Carefully pour the alcohol because it will start to boil.Continue until you have enough non-boiling liquid to use.The bottle should be filled about 1/3 of the way up.The gas is carbon dioxide.Don't breathe the gas directly when working in a well-ventilated area.
Step 6: The items should be put into the flash freeze mixture.
For a few seconds, submerge your item of choice.It only takes a few seconds to freeze the objects, even though this solution doesn't work as quickly as liquid nitrogen.Try freezing a variety of objects to see how their properties change.Liquid nitrogen will bead and roll off of your skin, but this solution will stick to it and cause severe burns.It's a good idea to wear gloves and clothing that protects the skin from the mixture.
Step 7: You can fill a bottle with water.
Supercooling, water, also known as flash freeze, is an experiment that you can perform if you want to make a liquid nitrogen substitute.Supercooling water can only be done with distilled water as tap water will lead to premature freezing.Leave some space in the bottle when you fill it because water expands as it freezes.
Step 8: The water should be chilled undisturbed for 2 hours in the freezer.
During the cooling process, place the bottle in a spot that won't be knocked around.The temperature of your freezer will affect the cooling time.You can tell if your water is supercooled by placing a bottle of tap water in the freezer.When the tap water is frozen, your bottle should be liquid.Check the bottle of tap water every 15 minutes until it is frozen.Don't touch the bottle of distilled water.The distilled water can be left in the freezer for too long if it is also frozen.The water should thaw and be able to be tried again.
Step 9: There is a bottle of water in the freezer.
Remove the bottle from the freezer.A movement can cause a liquid to form ice.
Step 10: The water was frozen in a flash.
The crystallization process will begin if you shake the bottle.This is also known as snap freezing.
Step 11: Proper protective equipment should be used.
Dry ice is very cold and frozen in carbon dioxide.When handling it directly, use insulated gloves.Wear goggles to protect your eyes.
Step 12: Caution is needed when handling the solution.
Liquid nitrogen will boil off the skin and not cause immediate damage, but it will cause burns.The solution will cause burns with contact.While handling the mixture, always wear protective clothing.Make sure the solution is handled with care.
Step 13: There is a well-ventilated area.
Clouds of carbon dioxide are created by this solution.Carbon dioxide can be harmful in high quantities.Keep your face away from the gas as you work in a room with good air quality.If you start to feel light-headed, leave the room and walk outside.Take some deep breaths.The gas in the room should be dissipated before you return.Turn on a fan if the windows are open.
