what part of the water cycle have invisible ink involved
The way invisible ink works depends on the method used to make it.
There are references to it all the way back to the 1200's. I know the US government just released top secret papers from WW1 and included in this was directions to spies how to make invisible ink and how to find documents with invisible ink. Considering this was written in 1911 it is a eye opener.
Invisible ink isn't actually invisible. The writing done with invisible ink is invisible, and can be read only after applying certain treatments. For example, orange and lemon juices are invisible inks. Orange and lemon juices are perfectly visible, but when you write with them, the text becomes invisible. The text can be read only if the paper is kept under ultraviolet light, or if it is slightly heated.
The conclusion to making invisible ink is that it is a fun and creative way to hide secret messages. Different substances like lemon juice, milk, or baking soda can be used to create invisible ink that reveals its message when exposed to heat, light, or another chemical. It's a simple yet effective method for keeping information hidden until it's time to reveal it.

Yes, baking soda can be mixed with water to create invisible ink. When the solution dries on paper, the writing becomes invisible and can later be revealed by applying heat or a second solution (such as vinegar).

Writing with milk on paper will be invisible (or nearly so) , Heating the paper will scorch the milk first and make it visible.
The good old fashioned way- water and soap. :)
