"Method One
The simplest method is to use lemon or onion juice to write with and let it dry. To reveal the writing, heat the paper with a iron, or other heat source.
Method Two
A more sophisticated approach uses an acid or base to write with and a pH indicator to reveal the writing. (pH is a measure of how acidic or alkaline a substance is - a pH of 1 is extremely acidic, 7 is neutral, and 14 is extremely alkaline). pH indicators change colour when mixed with acidic or alkaline substances.
To write with: White vinegar (which contains acetic acid) is probably the most convenient source of an acidic 'ink'. To make an alkaline 'ink' try a mixture of baking soda and water (around 50/50). With a small paint brush, write on a piece of paper using your chosen 'ink' and allow it to dry.
To reveal the writing:There is a natural pH indicator (a pigment called flavin) found in apple skin, grapes and red cabbage (amongst other things). Boil half a red cabbage in 5 cups of water. Filter out the cabbage, and spray or paint the juice over your invisible writing. I tried doing this with apple skin (I imagine this is only red apples), which also worked.
If you just want to see the pH indicator working, put a little of your cabbage/apple juice in the bottom of a glass and note the colour. Now add some white vinegar, noticing the colour change. Next add some baking soda. You will see the colour change back again. Enjoy :-) "

What is the hypothesis of an invisible ink?
The hypothesis of an invisible ink could be that the ink will become visible when exposed to a certain type of light or heat, based on the properties of the ink's chemical composition.
What liquid works best in making invisible ink lemon juice or baking soda?
Lemon juice works best for making invisible ink compared to baking soda. When heated or dried, the lemon juice oxidizes and turns brown, making the writing visible. Baking soda is not an effective choice for invisible ink as it does not have the same chemical reaction when exposed to heat or other substances.

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.

It's a simple yet effective method for keeping information hidden until it's time to reveal it.
What is the purpose of making invisible ink?
The purpose of making invisible ink is to write messages that are hidden and can only be revealed under certain conditions, such as heat, UV light, or a chemical reaction. It can be used for secret communication, security purposes, or fun activities like invisible ink pens.
Can you do the invisible ink experiment with lime?
