Invisible Ink

© MarcT


Lemon juice
Quill or cotton swabs (Q-Tips)
Heat source (toaster, stove element, embossing gun, hair dryer, etc.)


The last step of the instructions should never be attempted by kids without parent surveillance. Also, handle the paper carefully as it could catch on fire.


Dip the quill or cotton swab in lemon juice and write your message on your piece of Muggle paper.

Note: Experiments with invisible ink on parchment paper led us to believe it doesn’t work. The parchment just catches fire without revealing the invisible ink. A spell against Muggles the wizards have put on it, probably.

Make sure to dip your quill or cotton swab often in the lemon juice so you have enough invisible ink on it at all times.

To reveal your message, place your parchment or Muggle paper over a heat source and watch the message appear on your page. Almost like real magic!

Please note that the patterns and tutorials you find here have been designed by Harry Potter fans all over the Internet. The authors alone hold the copyrights and licences to these patterns and tutorials, which means you CANNOT use their patterns to make something that you will sell to others afterwards. You can use them to make things for yourself. You can make some for your friends and ask them to pay for supplies. You CANNOT, however, ask them to pay you to do it as though you had created this pattern by yourself, or try to sell you crafts to a local store.

Think about it. Would you take a Prisoner of Azkaban book, photocopy it, put your name in big red letters on the front cover and try to sell it in your local library? The answer is, obviously, no. Well, selling crafts you have made but not designed would be just as bad!

Also note that the tutorials, recipes and patterns found here have not been tested and that The Leaky Cauldron’s Harry Potter Crafts section is not responsible for any mistakes they may contain. If you do find something wrong in one of them, however, please e-mail us to let us know.
