You can use invisible ink to play hidden messaged games and pranks. For example, you can write a secret message on a piece of paper and hide it somewhere for someone to find. When they do, they can use an UV light or black light to reveal the message. You can also hide messages around the house or in the office and challenging people to find them using a UV torch or black light. You can also make your own invisible ink by mixing some common ingredients, like white vinegar and iodine, with a bit of water. This is safe to use on clothing and other materials and it should reveal a faint green or yellow tinge when held up to a light.
