In color theory, a purple is defined as any non-spectral color between violet and red (excluding violet and red themselves). The spectral colors violet and indigo are not purples according to color theory but they are purples according to common English usage since they are between red and blue.
Dry ice fog is a thick, dense, low-lying fog created exactly the way fog in nature is. created, by condensing water vapor out of the atmosphere. We use dry ice (the. solid form of carbon dioxide) to condense the water vapor out of the air. Dry ice. fog contains no chemicals, glycols, or oils, and is truly a water based fog.
When the water gets colder than 50 F, the Dry Ice stops making fog, but continues to sublimate and bubble. The fog will last longer on a damp day than on a dry day. HOW TO MAKE FOG For each 15-minute period put 5 to 10 pounds of Dry Ice into 4 to 8 gallons of hot water.This will make lots of fog depending upon the temperature of the water and the size of the pieces of Dry Ice.Hotter water will make more fog.hen the water gets colder than 50 F, the Dry Ice stops making fog, but continues to sublimate and bubble.
