Bridges built with only popsicle sticks and white glue were driven to their breaking points during the annual Popsicle Stick Bridge Building Contest sponsored by the Younger Member Forum of the American Society of Civil Engineers on Feb. Competitors had designed small bridges — 24 inches long and weighing under grams — that were both strong and aesthetically pleasing. They were judged for creativity, and then subjected to the pressures of a hydraulic press until they snapped. The bridge taking first place held pounds before breaking.

The Physics Of Bridges

Coffee stir stick model Plan for a 30cm bridge Hey Frank, we took first place in the technology category!!! Kim Properly assembled, the bridges in the above plans can carry 1, times their own weight but they are not the ultimate design. Use them as a starting point. The parts are few and easy to duplicate, so you can use your time more efficiently evaluating different configurations. Make several bridges and test your ideas. When you test the load limit of your bridge, catastrophic failure is unlikely. As soon as the first glue joint pops, repair it and think how you can reinforce that weak point.

10+ DIY Popsicle Stick Bridge Designs and Tutorials

The popsicle stick bridge is a classic science demonstration and competition. Every year many students world-wide build bridges made soley from popsicle sticks and glue, to see which designs can hold the most weight. We built one, using maybe sticks, give or take a few. Not expecting it to hold much weight, we were surprised by how strong it ended up being!

We ask a lot out of our bridges. We expect that our bridges will support a great deal of weight and that they will last for a long time. Bridge designs have improved a lot in the past centuries and our understanding of the physical principles of design, along with the invention of new materials has made it possible for people to design and build bridges that our ancestors could never have dreamed of.
