    I taught this first thing in the morning so that the invisible ink had time to dry and the kids could discover the hidden message before going home. Unfortunately, I forgot my blow dryer and I didn’t have an iron, so my only option was to use grape juice. It still worked, but there were some kids who did not follow the directions. Their invisible ink did not appear when their partner tried to uncover the message. I think next time I do this, I will need to have some ingredients already prepped for kids who don’t follow directions to ensure this doesn’t happen again. The kids who followed the directions had a good time uncovering the hidden message and learning about detectives.
