Here is a video playlist I created from youtube of selected popsicle bridge movies. You can see a variety of testing methods used in these videos. You can also see a lot of people not wearing eye protection, which is not a good idea. Always wear eye protection when testing a bridge.
I have always wanted to build a model suspension bridge, and finally I have finished one. This is a popsicle stick suspension bridge. I created it from scratch, coming up with the design on my own. After testing it to failure I learned quite a bit about how suspension bridges react to loads. This model suspension bridge uses popsicle sticks as the main building material. The decking is cardboard, and the “cables” are 550 parachute cord (military surplus)
Do not ruin your bridge from the start by using bad popsicle sticks. Learn what the best popsicle sticks look like, and how to sort through all the bad ones.
This is a popsicle stick bridge I built while in the last few weeks of my fall college semester. I used 924 popsicle sticks to build this bridge. This bridge was 5 feet long, 10 inches tall, and 8 inches wide. I had to sort through 2600 popsicle sticks to find enough usable ones. The first testing of the bridge consisted of 220 pounds worth of weights. The second testing included putting a piece of plywood on top of the bridge and me standing on it (170 pounds). We noticed that one end diagonal chord was bending tremendously, so I decided to call off any more testing until I could repair that one piece
This is a video I found on YouTube of an excellent bridge built for the Troitsky Bridge Building Competition. The only materials allowed for this competition are popsicle sticks, toothpicks, dental floss, and white glue. This is a very impressive bridge. It weighed 1.17kg and held 805kg. That gives it an efficiency score of 688
The American Society of Civil Engineers has been putting on an annual popsicle stick bridge competition for high schools in western Washington for the last 13 years. Last year, I entered with a 350 gram, 30 inch long bridge that carried 567 pounds under their hydraulic press. They score the bridges on efficiency (I won at that!) and aesthetics.
This is quite an interesting popsicle bridge video. The maker claims it is the “ultimate popsicle bridge design” because it held 600 pounds. He also states in the description that he spent a large amount of time optimizing the Warren Truss. This is also probably part of his “ultimate design” claim…
Here is a video from youtube that is a young man giving advice on building popsicle stick bridges after building one of his own. I like his thought process although I don’t necessarily agree with everything he says. What do you think? Notice when he says he sacrificed making triangles to add beauty to the bridge. Do you think this was acceptable? What would you have done?
Here is the story of the Prairie Popsicle Stick Bridge told in video format. As far as I know, this is the longest working popsicle stick bridge that a person can walk across. If you know of a longer bridge that does the same, please let me know. The largest popsicle bridge was built back in 2008 in my dorm room at Prairie Bible College. For many nights I slept on the floor, as I was using my bed space as a worktable to glue the bridge together.
