My Bridge is Big!
I built my bridge on the foundation of triangles because any engineer will tell you they
are one of the strongest shapes. No matter where you put pressure that other two sides of
the triangle pick up the excess pressure. I decided to build the triangles into boxes so
the support would spread out over a much greater area. I also added extra glue to the
joints to strengthen the corners that did not match up really flush. In doing so I
created joints that were not entirely straight but hold up just as well. I also cut the
toothpicks so I could use whole ones as hypotenuses. Many were thrown out because they
were broken or had defects in them.
Many difficulties I encountered were not having enough fingers to glue the four sides
down. Also it was a huge mess when the glue bottle became clogged and would not pour out
until you squeezed it very hard. Well it then came oozing out all over your bridge and
wasted like half the tube all over the wax paper or your mother's nice table. 
It was also very hard to get the toothpicks to stay in the upright position and when you
moved a slight bit either way the toothpick on the other side would fall over. 
Mechanical engineering involved in the bridge building process included finding out that
45-degree angles were the strongest and that mass and stress put on these angles broke
after the toothpicks were bent. Some careers include architecture, masonry, carpentry,
astronomy and being a high school physics teacher.
