Are Christmas and Halloween getting closer?
Has your child eaten up too much chocolate and other sweets, and what's more, he says it is not enough?
Are you tired of telling him to stop it, or have it in moderation?
Doesn't he believe there may be too much sugar in his body and it is harmful?

Prove it!

Using this application you can make him fool saying this application is able to establish the level of sugar in the saliva. Of course it is not true, it is only an iPhone, but your task is to make him believe it. There are two hidden buttons above on the display. The left upper part of the display shows normal level of sugar, the right part shows very high level of that. Before handing him the phone push the left or right button (it depends on what result you want to demonstrate), basically it shows high level. Then show him how and where to lick the display (the part below) and there is nothing to do left but excitedly wait for the results saying "wonder if the level is low ... Oh, God, itís astronomically high!" Consequently you can say: "Now you can see, you mustn't eat so much sugar."

Important!
Do not forget to clean the display properly from the bacterial pollution before licking. Remember, you probably use it with your fingers!
