The Poof Trucks - I think we will use some type of Poof Product, and going with the whole "Superbowl of Science" quote and the fact that we are holding the Nats. at the site of the 2004 Superbowl, I'm guessing Footballs (See below as well for more reasoning).
( y = ax(2) + bx + c ) - WARNING this explanation is long-winded!! LOL
Anyways, I think this has little to nothing to do with the actual motion of the playing objects, since a parabola is not defined by the law of "what goes up, must come down" rather "what goes down must come up" and we already have the parabolic "bowl" shape in the Astrodome. - I actually believe that since the equation is a Quadratic equation that is a fundamental in Trigonometry we should explore further the shape of the playing field here, and I am torn between a square or a triangle.
Two reasons, 1-The word Quadratic is derived from the Latin word "quadrare" which means "to make square". Because the area of a square that measures x units on each side is x^2, we refer to equations that can be written in the form of "ax(2) + bx + c = 0 as equation that are quadratic in x.
Reason 2. Since the Quadratic equation is a fundamental equation in the field of Trigonometry, and Trigonometry is defined as: The branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based on them, particularly the trigonometric functions.
So again, I think either a square or a triangle shaped playing field.
Also, since the Quadratic angle equation is dealing with the conical shape, Footballs!!
