Happy Science Friday, Friends! Today we’re experimenting with INVISIBLE INK!
TRUTH: it was not as cool as I had hoped. I don’t know what I expected. Maybe I just believed it would be MORE dramatic than it was.
TRUTH: Who cares! It was still so fun for my littles! Little P exclaimed more than once, “I can’t even SEE anything I wrote! It’s totally invisible.” Plus, the three-year-old only lasts for so long in any experiment. 🙂
TRUTH: It was so simple to put together, I’d do this again on a rainy day in a heartbeat.
I hope you have a Fabulous Science Friday!
To begin, there are several recipes for invisible ink, here. Pick you poison. We went with straight lemon juice. Gather a lemon, salt, paint brushes, paper, crayons.
Cut the lemon.
Squeeze 1/2 the lemon profusely, with great concentration, into a dish.
Commence in writing/drawing your SECRET MESSAGE in lemon juice on your paper.
When you are finished encoding your message, cover the lemon juice lightly in salt.
Dust the salt off after a few minutes, and allow the paper to dry completely.
Lightly color the entire picture/message/drawing. (That big Y on his paper was part of his SECRET MESSAGE!)
The SECRET MESSAGE should be a slightly DARKER than the rest of the color!
Science Friday, WE LOVE YOU!!!
