Disappearing ink is typically made from a combination of colorants, solvents, and compounds that allow the ink to become invisible after application. Commonly, it contains substances like phenolphthalein or other pH indicators that change color or become clear when exposed to certain conditions, such as changes in pH or evaporation of the solvent. The ink may also include water or alcohol as solvents to facilitate its application. Once the conditions change, the ink effectively disappears from the surface.
Disappearing ink is designed to eventually fade or disappear over time, but it may not come off of all surfaces easily. It is recommended to test the disappearing ink on a small, inconspicuous area first before using it.
Boy, put some Robitussin.
Disappearing ink is generally not considered poisonous, but its safety can depend on the specific ingredients used in its formulation. Many types are made from water and non-toxic dyes, making them safe for general use. However, some formulations may contain chemicals that could be irritating or harmful if ingested or used improperly. It's always best to check the label for safety information and use the product as intended.
Disappearing ink typically contains a substance like phenolphthalein, which is colorless in acidic conditions and turns pink in basic conditions. When you pour vinegar (an acid) into hot water, it alters the pH of the solution. If the disappearing ink is in a basic state, the vinegar effectively neutralizes it, causing the ink to reappear momentarily as the pH shifts. The heat may also affect the solubility and reaction rates, enhancing the visibility of the ink.
what was the ink made from in WW1
Ink.
No, disappear is a verb. The present participle disappearing is sometimes an adjective.(In Latin America, the Spanish word for "disappear" is used as a verb to mean extra-legal murder or detention, and the word disappeared is an adjective.)
when it was made
"You guys made me ink!!"
becuse the ink made your hands dirty
No, a pen can be made from various materials e.g. a quill, metal, plastic, but not ink, the pen is filled with or dipped into ink prior to use.
If you mean India ink, the answer is no. India ink in made with carbon black and is not inherently waterproof. It must be made waterproof the same way other inks are made waterproof, by the addition of certain chemicals and compounds.
