Today's YGK Science Club: "Invisible Ink"

We chose "Invisible Ink" as the theme of today's YGK Science Club.
First, the teacher showed us a piece of plain white paper.
Then, she stroked it gently with a special liquid.
And, Ta-daa!  A pattern showed up!
The children went like "Woah" or "Oh!"
We had a super fun Saturday!
