Hide a message in Musical Sheet
Hello guys !
I'm organizing a scavenger hunt for my wedding and I want to hide a message in the musical sheet on the piano that I have at the wedding place.
The musical sheet are written already but I want to hide a message in it with invisible ink. Do you have any inspiration or ideas on what to do ?
Thanks in advance !
(the answer should be a 4 digits number (to unlock a chest))
