invisible ink is available..
do you believe that? why not..let's see how to make it...
if you really have a secret letter and you don"t want everyone read it,then you get to hide it of course, but how to do it?
things you have to prepare
1. lemon, cut it into two
2. cotton bud
instructions:
after you curve the lemon, take its water after that pour into a glass, then get in the cotton bud into the glass, at last you can write your secret by using the cotton bud as pen and the lemon water as the ink..your secret will be safe.
then how to read it?
it's simple...just raise the letter towards the sunlight then your secret will appear..
