What happens when an alcohol base pen meets another alcohol base? What happens when it meets a water base?

When an alcohol-based pen comes into contact with another alcohol-based substance, such as another alcohol-based ink or a rubbing alcohol, the two substances tend to mix and dissolve into each other. This is because alcohol is highly miscible, meaning it has the ability to uniformly mix and dissolve with other substances of a similar nature.

When an alcohol-based pen encounters a water-based substance, such as water or a water-based ink, the results can vary. Alcohol and water are not typically miscible in large quantities, meaning they do not easily mix together. Consequently, when an alcohol-based pen touches a water-based substance, it often causes the ink to smear or bleed, potentially resulting in a distorted or blurred image.

To summarize:
- When an alcohol-based pen meets another alcohol-based substance, they will generally mix and dissolve into each other.
- When an alcohol-based pen meets a water-based substance, such as water or a water-based ink, the interaction can cause smearing or bleeding of the ink.
