How to Write a Secret Message with Invisible Ink!

Описание

When life gives you lemons... make invisible ink! Every secret agent knows how to read and write secret messages, and now you can too :)

This video teaches you how to make three different types of invisible inks:
- heat activated invisible inks (written in either lemon juice or milk, and revealed by heating the message in the oven)
- chemical activated invisible inks (written in bi-carb soda, and revealed by painting either grape juice or turmeric over the message)
- UV light activate invisible inks (written in washing powder, and revealed by shining a UV light on the message).

If you watched to the end, you would have heard that this is my last video for the year :( But don't worry, I'll be back in February 2021 for more Silly Science! What did I see at the end of this video... that secret will soon be revealed... :)
