The document describes a science experiment involving making invisible ink from lemon juice. It provides the materials needed, which include half a lemon, water, a spoon, a bowl, cotton bud, white paper, and a lamp or light bulb. The instructions explain how to squeeze lemon juice into a bowl with some water, mix it with a spoon, use the cotton bud to write a secret message on paper with the lemon juice mixture, and wait for it to dry. Then when ready, heat the paper under a light bulb to reveal the hidden message as the lemon juice oxidizes and turns brown.

Lemon juice is an organic substance that oxidizes
and turns brown when heated. Diluting the lemon
juice in water makes it very hard to notice when you
apply it the paper, no one will be aware of its
presence until it is heated and the secret message is
revealed. Other substances which work in the same
way include orange juice, honey, milk, onion juice,
vinegar and wine. Invisible ink can also be made
using chemical reactions or by viewing certain
liquids under ultraviolet (UV) light.
d) ___________________________________
 Squeeze some lemon juice into the bowl
and add a few drops of water.
 Mix the water and lemon juice with the
spoon.
 Dip the cotton bud into the mixture and

 Wait for the juice to dry so it becomes
completely invisible.

message or show it to someone else, heat
the paper by holding it close to a light bulb
