We wanted to see if the bullet proof fountain pen ink was really bullet proof.
It really is.
We ran the test with the inks listed in the previous picture.
This is after letting the paper soak for two days.
The left side was soaked in tequila and the right side soaked in water.
We did not have any rubbing alcohol so we used what we had on hand.
The tequila dissolved the inks faster and also effected the fake sharpie.
Other than that the results were similar.
The lesson is not to sign a check or important document with fountain pen ink that is not ink fast.
