How can you make invisible ink with ; water, cooking oil, or vinegar, lemon juice , rubbing ALCOHOL ?
Is it properly(rubbing alcohol) alcohol works best in making invisible ink because it can dry easily.
An ounce or two of lemon juice or vinegar in a cup or bowl
cotton swabs or paintbrush
thin white paper
a lamp with a 100-watt bulb
Think about what you want to say in your mysterious note!
Next, dip the cotton swab or paintbrush (even a toothpick will work) into the lemon juice or vinegar.
Write a message on the paper.
Wait for it to dry completely. It should be invisible when it dries.
For this step, you should ask an adult to help you, because 100-watt light bulbs are very hot. Hold the paper over the light bulb (don’t stare into the light!), moving it slowly so that all possible parts of the paper are exposed to the heat of the light bulb.
The mystery message should appear as the paper heats up.
