Projectile motion by Volleyball

Probability of not getting me in my home at 5:00PM to 6:00PM is tending to 1. I frequently go to playing ground everyday to explore some mathematical beauty which are hidden in nature! Some friends are playing volleyball.. 

 

  When they throw the ball to each other they always make a special curve. They cannot make the curve other than the previous one! What the curve I am talking about? The special PARABOLA, which have eccentricity 1. Now a question will be raised 'what is the weird sounding "Parabola" is?' Okay, let's explore. We will need some clay and a sharp knife. We have to make a solid cone by the clay and have to cut the clay like the this.
