What you'll need:
lemon juice
water
cotton swabs
note paper
What to do:
Mix a tablespoon of water with a tablespoon of lemon juice.
Dip a cotton swab into the water-juice mixture (they will serve as your "pen" and "ink"). Then use the swab to write your message on the paper.
With a regular pen, write a simple instruction on how to "decode" your message. Tell your friend to hold the note near a lit light bulb. As the lemon juice heats up, your message will appear like magic!
What happens:
Lemon juice contains carbon compounds. As the juice heats up next to the bulb, the compounds breaks down to form carbon, a black substance. Then your secret message is revealed and no longer a secret!

After the huge storms that rolled through here last night, I don't see us getting outside today
