Put 2 Tablespoons of lemon juice into a small bowl. Dip the
toothpick into the bowl and write one letter of your message on the paper.
Repeat this for each letter.
After the juice dries for ten minutes, it is ready to be read.
Put the paper in front of the light bulb. Be sure the shade is off the lamp, and
that you don’t touch the hot bulb. As the paper heats up, the juice will turn
brown and you will see the message.
Caution: Be sure and keep an eye on your children if they are
young. If the paper comes into contact with the bulb, it could cause a fire.
