first of all, hello! here's help

 

 

take some lemons, slice them and get their juice. with a paintbrush or finger write something on white paper. let it dry. when it is dry, hold it over a candle, light bulb or anything which generates heat. The writing will turn brown.it will happen because the heat will burn the lemon juice. wish i helped. Bye:-)
