Dear Parents and Supervising Adults,

The Experiments

Centuries of Secret Messages

Disappearing inks have

been used to send secret

messages for centuries,

but not just by spies. In

2 AD, Ovid, the Roman poet,

wrote instructions on

how secret lovers could

use milk and charcoal to

exchange messages in

his Ars Amatoria (Art of Love). Prisoners would

also used this technique to communicate with the

outside, like Mary, Queen of Scots, who wrote to

her supporters using alum, which could then be

dipped in water to reveal her message.

Magic Pens

You can start creating confidential messages

using the two secret pens. Using the white pen,

write something on the notepad — classified

instructions, notes from your investigation, or

maybe a list of suspects! Within a few seconds,

everything you wrote will have disappeared. The

only way to read the message now is to swipe over

the notepad with the blue pen. Now try it the other

way around. Have your partner respond using the

blue pen, and reveal the secret information with

the white pen!

WARNING: Do not try this experiment without

an adult present. Children should NEVER use

the stove or oven without adult supervision.

Tip: Be “inconspicuous”

Inconspicuous means not attracting

attention. Sending someone a blank piece of paper

might be a little suspicious, so take a normal pen or

pencil and write or draw something non-confidential

in an area where there isn’t a secret message

waiting to be revealed. This is why the included

notepad has the bogus message preprinted on it.

WARNING! Not suitable for children under 3

years. Choking hazard — small parts may be

swallowed or inhaled.

💡

With the help of an adult, try using the heat from

the oven to reveal a secret message written in

one of these household items: milk or juice from a

lemon, apple, or onion.

Pour one of the

liquids into the

petri dish

and use

the brush

to write

a short

message

on a piece

of paper from

your notepad.

Reappearing Ink

Once it dries, the

message will no longer

be visible. Place the

sheet of paper in

the oven at

200 °C / 400 °F for

five minutes. What

do you observe? The

writing turns brown!

Exchange confidential messages with

your fellow agent using disappearing and

reappearing ink that only the two of you

can read! Using either of the two secret

pens, you can write a message that, once

dry, becomes invisible. The other pen will

not only reveal the information, but you can

also use it to send your reply.

Secret

Message Tools

Disappearing / Reappearing Ink

Most modern erasable pens use

Thermochromic ink so that you can correct your

mistakes, but it isn’t truly “erased.” Thermochromism

is the property of substances to change color due to

a change in temperature. The ink in an erasable pen

turns clear at 60 °C/140 °F. When you rub it with an

eraser, you create friction, which causes the molecules

on the surface to move faster. This causes heat (just

like rubbing your hands together when you’re chilly).

However, it’s just a color change, so you can make the

color reappear by cooling the ink to 4 °C/40 °F. You can

do this by putting it somewhere cold, like the freezer.

Send someone a secret message this way, and don’t

forget to think of a sneaky way of telling the recipient to

put the paper somewhere frosty.

💡

Milk and the other household liquids contain

carbon compounds, which are colorless

(or almost colorless) at room temperature.

The heat from the oven breaks down these

compounds and releases carbon. When carbon

comes in contact with oxygen, a chemical

reaction called oxidation occurs, turning the

substance brown.
