Some pranks with invisible ink you could do include writing secret messages on surfaces, then revealed with UV light, decorating a piece of clothing with invisible ink that can be seen under ultraviolet light, and writing secret code messages on leaves which can be decoded with a Ultra Violet Light decoder.
