I am currently doing an experiement/project where we want to use paper and then
spray some 'magic solution' on it such that the paper changes colour. Will the
paper turn pink if baking soda solution is sprayed onto paper and dried, then
phenolphthalein is sprayed onto it? 

Also what are some alternatives? Like I have heard of red cabbage juice etc, but
the experiment that we are trying to do should be a reversable reaction. Thanks!
