Calculations

Data
1 popsicle stick = 1.1 g
1 popsicle stick + one popsicle stick volume of hot glue = 4.5 g

Using the data above we concluded that the same volume of hot glue as one popsicle stick weighed much more than the popsicle stick (3.4 g is found using subtraction to represent the glue's mass vs. the 1.1 g of a popsicle stick)

Inertia of Popsicle stick in multi-dimensions
Which way is stonger?

The Popsicle Stick Horizontal-

The Popsicle Stick Vertical-

The Vertical Popsicle Stick has much greater Inertia, therefore much greater force is needed to strain or break the stick.

mass suspended from the bridge : bridge's mass ratio
After our final test, we found one calculation which we found to be incredibly impressive.  Our bridge weighed in just over 200 grams (201 to be exact).  Our bridge successfully held 128 lbs before the weights crashed to the floor as seen in our video.  Using the conversion factor from pounds to grams, (1 pound = 453.59 grams), we found out how many grams our bridge held (58,059.82 g).  By dividing the suspended weight by the weight of the bridge, we found that our bridge was able to support x300 its weight!
