If you have little time, you can use a lemon to make invisible ink. The trick with lemon juice is that it IS invisible ink. You only have to press the juice out of a lemon, dip a crown pen or pointed feather in it, and write your secret message. Because it's colourless, it can't be seen after drying.
Only when you heat the paper, above a candle or with an iron, the lemon juice ink will discolor brown, and you'll be able to read it again.
