Home Made Liquid Nitrogen

You can make your own homemade liquid nitrogen using readily available materials. It's not really liquid nitrogen, however, but cryogenic-temperature alcohol. The chilled alcohol can be used for many liquid nitrogen projects, such as freezing flowers or other materials. It is not suitable for ice cream or anything edible. Also, although this "poor man's liquid nitrogen" is very cold, it doesn't vaporize off your skin like true liquid nitrogen, meaning it can give you frostbite very easily. Avoid skin contact and use all the safety precautions you would use with nitrogen.

Homemade "Liquid Nitrogen" Materials

• dry ice
• 99% ethanol (lower percentage will work but you'll get a gelatinous cryofluid)
• Insulated plastic container (don't use glass because extreme temperature changes may cause it to shatter)

Prepare the Homemade "Liquid Nitrogen"

   You've two ways to do this

1. Alternatively, you can pour the alcohol directly over the dry ice. This is easier, but you won't have control over the temperature of the dry ice, so it's possible your alcohol will freeze.

Otherwise just follow below steps:

Pour the Ethanol alcohol into a plastic insulated container 

Keep dry ice into another insulated container

 Slowly add dry ice to bath the Ethanol, please do not handle with bare hands

Place shaker base to hold anything you wish to freeze

You may use electric hand blender to mix the ingredients 

CAUTION

The chilled dry ice/alcohol bath is very cold. If the chilled coolant contacts your skin it can cause almost instant frostbite. Use due care in handling the cold bath 

These method can be use in preparing any frozen cocktails and Ice cream, it's not recommended to drink anything mix with the coolant liquid !!!
