Homeless Man's Liquid Nitrogen

It's liquid DFE(1,1,-difluoroethane) that's commonly sold in certain stores as computer duster. It is used when neither dry ice or liquid nitrogen is obtainable. It's usually used for science, to freeze things, or just for fun cooling thermometers, water, or some insects. The computer duster can is used for dusting off the dust from computers using the DFE gas. however, when turned upside-down, it provides a frostbite causing super-cold liquid that's -25 degrees Celsius(-12 degrees Fahrenheit) or colder. It is sometimes(very very rarely) used to try to liquefy formaldehyde or other gases, but due to the toxicity of these gases, a gas mask is recommended. It can liquefy butane, a far less toxic, but highly flammable gas. Getting Homeless man's liquid nitrogen on skin can be deadly, as frostbite can occur. It's a cryogenic liquid.
Dude, I just froze some cockroaches, a container of water, and liquefied a gas using Homeless man's liquid nitrogen.

Nitrogeno 

The way every Italian reacts to seeing the word "Nitrogen" because apparently in 2021 no non-chemist Italian whatsoever understood that "Nitrogen" is actually "Azoto" in italian and not "Nitrogeno".
Italian non-chemist: HA APPENA MESSO IL DITO NEL NITROGENO LIQUIDO, QUESTO È PAZZO
Italian chemist: SI CHIAMA AZOTO. Giuro che se dici un'altra volta "Nitrogeno" ti ammazzo.

Smart man's liquid nitrogen 

Smart man's liquid nitrogen is dry ice mixed with 1,1-Difluoroethane. The boiling point of 1,1-difluoroethane is -11.29°F (-24.05°C) while it's melting point is -178.6°F (-117°C). The sublimation point (the point at which a substance sublimes, or goes from a solid directly to a gas) of dry ice (solid carbon dioxide) is -109.2°F (-78.46°C). Smart man's liquid nitrogen stays at around -78°C as long as you keep supplying more dry ice. Then the dry ice runs out and it heats up until it reaches -25°C where it becomes homeless man's liquid nitrogen. Then the 1,1-Difluroethane (can be found in computer duster) slowly boils away until it becomes gaseous 1,1-Difluoroethane. You can keep chemical reactions cool with smart man's liquid nitrogen and once it becomes homeless man's liquid nitrogen, you can use a funnel and a plastic soda bottle to store the liquid difluoroethane under pressure and label it and put it in the lab freezer.
I kept my chemical reaction extra cool with smart man's liquid nitrogen.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
