INVISIBLE WRITING

1 laxative tablet (white)
1 Tbsp. rubbing alcohol
cotton balls
household ammonia


Mash the tablet into the alcohol. Be sure the tablet is entirely dissolved. Write a message on paper with a paint brush that has been dipped in the solution. As the solution dries, the writing disappears. To develop the message: dampen the cotton balls in ammonia and dab on the page. The writing will reappear.
