Citrus Secrets Experiment: Exploring Invisible Ink with Lemons

This experiment is designed to demonstrate a fascinating chemical reaction, turning a common ingredient in many kitchens, a lemon, into invisible ink.

Ingredients:

  • 1 Fresh Lemon
  • Water
  • White Paper
  • Cotton Swab or Paint Brush
  • Lamp or Iron (Hot source)

Instructions:

Step 1: Prepare the Juice

Squeeze a lemon into a bowl and add a few drops of water to the fresh lemon juice. This will be your "invisible ink."

Step 2: Create Your Message

Dip a cotton swab or fine paint brush into your mixture of lemon juice and water. On a piece of white paper, use the moistened tool to write a secret message or design.

Step 3: Let It Dry

Allow your secret message to dry entirely on its own; do not accelerate the process by applying heat at this stage. Once the juice has dried, your message should be practically invisible.

Step 4: Reveal the Message

To make your message visible, you'll need to apply heat. Position your paper near a light bulb or heat source (not too close, safety first). As it warms, the areas where the lemon juice is absorbed should start to brown before the areas of the paper that were left plain, revealing your secret message.

Step 5: Discuss the Results

This is a perfect time to talk about why the lemon juice becomes visible when heated. When heat is applied, it causes a chemical reaction that turns the lemon juice brown, making your message visible.

Please supervise children while conducting this experiment to ensure they handle the heat source safely.


Secret Messages with Lemon Juice

Secret Messages with Lemon Juice Experiment

A wonderful and exciting STEM experiment that allows kids to understand how heat can reveal messages written in citrus juice. Fun and educational!

Ingredients:

  • Lemon Juice: Natural or bottled, either works fine.
  • A Small Paintbrush: For painting your secret messages.
  • White Paper: To write the secret message on.
  • Heat Source: A hair dryer, lighter, or heat lamp can be used for this. Note: Adult supervision needed for this step.

Instructions:

  1. Squeeze the Lemon: If you are using a natural lemon, cut the lemon in half and squeeze the juice out into a small bowl.
  2. Write your Message: Dip the paintbrush into the lemon juice and write your secret message on the white paper. Remember, the message will be invisible after the juice dries.
  3. Let it Dry: Let the lemon juice dry. You might need to wait for a few hours until the paper is dry to the touch.
  4. Reveal the Message: This is where adult supervision is needed. Pass your heat source quickly over the paper, ensuring to not hold it too close. The heat will react with the lemon juice and reveal your secret message.

Heat Sensitive Writing Experiment

Heat Sensitive Writing Experiment

Objective:

Create invisible ink and reveal the text by heating the paper, as a fun way to understand a basic chemistry reaction.

Ingredients:

  • A lemon or a bottle of lemon juice
  • A piece of white paper
  • A cotton swab, paintbrush, or stick to write with
  • An iron or a lamp bulb
  • Adult supervision (this experiment involves the use of heat)

Instructions:

  • Squeeze a lemon or open a bottle of lemon juice into a bowl.
  • Soak the cotton swab or paintbrush into the lemon juice.
  • On your piece of paper, begin writing your message using the lemon juice-soaked tool. Be sure to dip it back into the lemon juice for more "ink" as needed.
  • Allow the paper to dry completely. This might take some time. Your message should be invisible or barely visible on the dry paper.
  • Now for the fun part! Here is where adult supervision is important. Using the iron on a low heat setting (no steam), gently iron the paper. Alternatively, you can hold the paper over a light bulb or lamp. The heat will cause a reaction with the lemon juice and your message should become visible as the juice heats up and browns slightly.
  • Note: Be careful to not overheat, as this could cause the paper to catch fire.

What just happened?

The lemon juice is an organic substance that oxidizes and turns brown when heated, revealing the message. This reaction is a typical example of how heat speeds up chemical reactions.


Chemical Reaction Detective Experiment

Chemical Reaction Detective Experiment

Overview

In this DIY STEM experiment, children will learn how acid-base reactions can be used to create invisible ink. The experiment involves using baking soda (a base) and grape juice (an acid) to create the ink. Once the baking soda dries it becomes invisible which can be revealed using grape juice.

Ingredients

  • 1 tablespoon of Baking Soda
  • 1 cup of Water
  • Grape Juice
  • White Paper
  • A paintbrush or a cotton swab

Instructions

  1. Prepare the Invisible Ink: In a bowl, mix together one tablespoon of baking soda with one cup of water. Stir until the baking soda is completely dissolved.
  2. Write Your Secret Message: Using a paintbrush or a cotton swab, dip into the baking soda and water mixture and then write your message on a piece of white paper. Allow the message to dry completely. Once dried, the message will become invisible.
  3. Reveal Your Secret Message: To reveal the secret message, paint over the invisible ink using the grape juice. Since grape juice is acidic, when it comes into contact with the baking soda on the paper, it undergoes a chemical reaction that makes the baking soda visible. Hence, revealing your hidden message.
  4. Investigate Further: You can challenge your child to identify the underlying science, which in this case is an acid-base reaction. If your child is older, encourage them to write out the chemical equation for the reaction.

Safety Precaution

This experiment uses materials are safe and non-toxic, however, adult supervision is still required. Make sure the children do not ingest the baking soda and water mixture, and do not get the grape juice in their eyes.
