please I would like to know how to make erasable ink.I have the needed material but I can't seem to find a way for the ink to flow from the marker pen.help me with detailed analysis please. Thanks
Detailed analysis as you call it, is not possible without further information. You say you have "the needed material". What are those materials? What type of marker pen are you using? What are you using to erase the ink? What type of paper are you using? What colour is the ink?
I started reading your question 3 minutes ago. In that time, I've thought of 41 chemical compounds that would meet your requirements but each of them requires different methods of delivery from pen to paper and they also require different ways of erasing.
Provide the info requested if you really want help.
