The 100 stick popsicle bridge challenge is on. This Howe Truss bridge uses 99 popsicle sticks, spans 21 inches, and holds 200+ pounds. It’s efficiency score is 678. This is an updated version of my old “Popsicle Bridge #3” which was the same length, but slightly different in construction.

We run a comp here at Albury High in Australia for our Yr 12 Engineering Studies students involving max. 50 popsicle sticks, PVA wood glue and 2m of extra strong thread. Structures have to span 400mm and are centrally loaded. Here’s a photo of our 2010 winner which weighed in at 69 grams and held 58kgs giving an efficiency using the formula on your website if i used it correctly of around 12000!

This is a very simple yet elegant looking bridge that I built over Christmas break. This bridge spanned 16 inches and was made from 48 popsicle sticks. It held 75 pounds, which was right at what I was expecting.
Here is a short, fun video showing creative bridge designs from very limited supplies. These bridges were required to be under 5oz in weight, but only had to span 8 inches. I like this video because it is pretty clear why each bridge failed. Can you see a major design issue that could be improved in most of these bridges? Notice that they do incorporate triangles, but they are missing a key member. The students were only given Cardstock Rubber […]

I have a bridge I built for a physics for engineers class I’m taking in cegep (QUEBEC). My partner and I didn’t have much confidence in it, but it blew the competition away! We primarily focused on keeping the weight of the bridge down. The bridge weighed in at 211 grams.

Building popsicle stick bridges is one of my favorite activities to do in my spare time. I have built many popsicle bridges over the years, and love coming up with new designs. A huge focus of my bridges is designing blueprints that are easy to build and structurally sound at the same time. You can purchase many of my plans and blueprints in my store.

Have you wanted to make a strong popsicle stick bridge that used 100 popsicle sticks or less? This popsicle bridge was made from 98 unmodified popsicle sticks and WeldBond glue. It was 21 inches long, 4 inches tall, and 4 inches wide. It weighed about 150 grams, and held 140 pounds. With less than 100 popsicle sticks, that is a lot of strength in this bridge. Its efficiency score was 424. This is the strongest popsicle bridge I have built […]

This bridge is supporting 191lbs of weight. It didn’t break, that was all the weight we could fit in the trash can. I believe this is close to the maximum load it could hold because the platform the jig is resting on was significantly bowed. The rest of the structure was rock solid. The construction of the bridge is popsicle sticks

This album highlights the Popsicle Stick Bridge that I entered into the Seattle ASCE Younger Member Forum’s Popsicle Stick Bridge Competition in 2009. This particular entry swept all first place prizes in every category: efficiency, aesthetics, and poster. It’s 30 inches long, 11 inches tall, 5 inches wide, weighs just under…

These are some pictures of a bridge I built mainly out of boredom, but also since I have an interest in engineering. It’s a large cantilever bridge, meaning it has two arms that extend beyond their piers that hold up a center suspended span. It’s 10′ 2″ long and as of right now is hanging across my bedroom ceiling
