How to Make Cheap Liquid Nitrogen at Home

Liquid nitrogen isn’t always easily available to most but this video shows how a cheaper form called poor man’s liquid nitrogen can be produced with relatively accessible materials right in your own home.

This cold concoction makes use of dry ice, two plastic soft drink bottles and rubbing alcohol to obtain a liquid gel mixture that cools objects at 110 degrees Fahrenheit (-78 degrees Celsius), compared to real liquid nitrogen at -320F.

It does look like the poor man’s liquid nitrogen performs reasonably well too, for re-enacting classic science experiments such as shattering flowers and leaves demonstrated in the video.
