A balloon is put on the ground. At the distance of 5-6 steps from it there stands the player who wants to make a penalty kick.
Before everything he's blindfolded and then asked to come back to the balloon and kick it.
From time to time you could make this game more difficult by rotating the person around for several times before he kicks the balloon.
It`s a real cool when the person having precisely made those 5-6 steps kicks the air, because he went in the incorrect way.
