Science for Toddler: Magic Ink (Spy Version)

The Making of Invisible Ink~

Invisible ink has fascinated toddler for generations *yay*

You might think that it would be difficult to make, but it’s not 😉

 

Note: This simple experiment is great for young toddler, but must be conducted with adult supervision because it involves using the kitchen stove or candle.

 

Materials You’ll Need:

  • some vinegar (you also can try this experiment with other liquids, such as orange juice, lemon juice, apple juice, onion juice and milk)
  • some white paper
  • a clean paintbrush (clean cotton swab or a toothpick)
  • kitchen stove (or candle)


Step by step guide
:

  • Step 1: Mission In Action
    Ask your toddler to pretend that they’re a spy on a secret mission, writing messages that would lead to big, big trouble if they were discovered.
    Make them choose their words carefully.
    *for this mission, I asked my kiddies to write their secret message to PaPa*

  • Step 2: Start It On!
    Guide your toddler to use the brush or cotton swab and write their message with vinegar on the paper.
    Don’t use a lot of vinegar and soak the paper. Use just enough to make a thin coating.
  • Step 3: Finish Line
    After finished writing, ask the person whom is a special agent *in our case, Papa is the one!* to receive the paper and help them to turn on the kitchen stove to a low heat.
    Very carefully hold the paper about a foot above the warm burner.
    If you don’t see results, you may have to make the burner a little hotter.
    Do not, however, hold the paper low over the burner.

Result: As the paper heats up, your toddler’s message will become brown and they’ll be able to see what was written.

You want to know why? (explain to your toddler):

Lemon juice and vinegar are mildly acidic, and acid weakens paper. The acid remains in the paper even after the juice or vinegar dries.
When the paper is held near a hot light bulb the treated portions of the paper burn, and turn brown, more readily than the untreated portions.

Have fun mommies!

Just be sure to follow all safety rules 😉

May all the best to you. Amin~
