Materials
Materials

cotton swabs or paintbrush

thin white paper

a lamp with a 100-watt bulb


Procedures
Procedures

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.
