is there any way to get a flatter stomach in 2 weeks?

im only 13 so i cant really go to a gym, or buy diet pills.
i want to know if there is ANY way (out of exercise…maybe tahitian/any dance)
that i can obtain a slimmer and flatter stomach in 2 weeks,
i only have 2 weeks.

Right now im trying to drink water more; and tahitain cardio every afternoon with my sister and before that i do this:http://www.fitnessmagazine.com/workout/abs/exercises/flatter-abs-in-2-weeks/
oh and i KNOW i cant “target loss”
so, i just mean i want pretty much stubborn belly fat to GO AWAY. Mahalo
