Model Bridge Design

This is the updated design of my Short Pratt Truss Bridge made from popsicle sticks. The only difference was the addition of 4 more popsicle sticks in key areas. I doubled up the angled sticks on each end, and made the lateral bracing into an X shape rather than a zig-zag pattern

This is a popsicle stick bridge I built using the Pratt Truss design. This bridge is 13.5 inches long, 4 inches tall, and 3.75 inches wide. This bridge weighed about 70 grams and held 73 pounds before breaking. I used 46 popsicle sticks to build this bridge. That gives it an efficiency score of 474

Here is a balsa wood bridge being tested to failure. You can tell how it breaks, which is pretty cool

This video has some excellent toothpick bridges. These bridges hold an incredible amount of weight before they break. You get to see it all on video

The Bridge Builder Blues is a fun little song I originally wrote back in late 2004. I forgot about it until the Science Olympiad season of 2006. I pulled it out, and with the help of my brother re-wrote the lyrics and came up with the music. Then in 2007 We made a music video [...]
