ABSTRACT
The purpose of my experiment was to see how area and force are related to pressure.

Three boards were prepared with nails.  One board held only one nail.  One board held many nail spaced 1 inch apart.  The final board contained many nails spaced Π inch apart.  Three balloons of equal size were then placed on each of the boards.  On top of the balloon another board was placed.  On this board heavy kg weights were placed. The amount of weight needed to burst the balloon on each of the boards was recorded.

PURPOSE
The purpose was to see how area and force are related to pressure.

Three boards were used with different numbers of nails on each.  One board contained only one nail.  One board contained nails spaced 1 inch apart.  The final board contained nails spaced Π inch apart.  Balloons were blown to the same size.  Each board had a balloon placed on it and then covered with another board.  On top of the board kilogram weights were placed until the balloon burst.  This was repeated 5 times and the data recorded.

The board with the single nail took the smallest amount of weight with  an average of 1.2 kg of weight.  Next, the board with the nails spaced Π inch apart took an average of  2.1 kg of weight.  The board with the nails spaced 1 inch apart took the most weight with an average of 5 kg of weight.
