Younger kids will enjoy building and playing with the bridge, while older kids can take the opportunity to learn about how bridges are designed the way they are. Make a simple bridge with duct tape and craft sticks in this fun STEM activity. Kids can think like engineers as they design and build a bridge to support toy cars. Once the base of the popsicle stick bridge is done, glue the side trusses on standing along the edge. I glued it and propped up some books along the side to hold them up while they dried.

(Verify with your instructor is this acceptable.) If you do this, you’ll create very strong, very rigid joints that are unlikely to fail. If you can’t use a dowel, you might still be able to strengthen the joints by drilling them and running a tiny piece of cable through as a tie. Now, we don’t need all the handrails, decking, etc, but what we see is the use of a tensioned cable to create the bottom cord of the truss. The cable is incredible strong and can be run continuous between the supports, reducing the number of connections that can fail in the structure. The other possibility is a weak popsicle stick, which started to fail and then brought the rest of the bridge down with it.

You could also use some clamps to keep them together. Attach the sides together along the top with another triangular pattern. We decided to make a truss bridge with our sticks. A Warren Truss bridge is made with equilateral triangle truss beams that divide out the weight on the bridge.

Build-A-Tool Contest
In statics, we learn about architectural elements such as arches, beams, buttresses, trusses, and vaults. The truss is one of the most important, and it’s widely used in construction. In its simplest form, a truss is a rigid framework of bolted-together triangles. Triangles are inherently strong and stable, and structures made out of them are also strong, rigid, and lightweight. If you want to use a different truss bridge design, go ahead and plan it out now.
Bridges across the globe make up some of the most beautiful landmarks on this Earth. However, it would be quite impossible to bring them to the kitchen table. Luckily, with a few bridge building techniques, a few popsicle sticks, a creative mind, and a few other household items, you can now build a glorious bridge of your very own. My conclusion based on these photos is that the lateral bracing on the left side popped off from the side of the bridge closest to you in the photo.
Step 8: Testing Phase
Burnishing is a technique used by professionals to achieve a certain appearance and is commonly used... Scientific American suggests exploring different shapes to find the strongest one for your project. Its applications range from STEM education to art projects and DIY home decor. Have one person gently lift the blue sticks while the other person slides in a second bamboo skewer. Younger kids will love it too, but may need more help.
Step 5: Get Bigger...
Just be careful to do proper testing of your model before attending any competition. Nevertheless, while participating, save up your time and resources to build a fresh one if anything goes wrong with your tried and tested prototype. Starting with a small weight, increase the load gradually while placing them at different points of the bridge to keep the weight well-distributed. You can use anything from small buckets of water to barbell weights and concrete blocks. If it fails, add reinforcements at the points of breakage. We first built our bridge without paint, and then decided to paint it because the sticks were blending in with the rug when we took pictures.
We were provided with about 60 sticks, a cushion of office pins and a tube of super-glue. I have attached a picture of the bridge we constructed, that eventually won the first place. I’m sorry I don’t have a better picture to show you. To connect a popsicle stick bridge, you can lay long sticks across the struts and glue them into place. If the sticks are not long enough, you can join them together by cutting and gluing them, using a stick for support at the bottom. Firstly, you will need to gather enough Popsicle sticks to build your bridge truss.

Video Tutorial for a Popsicle Stick Truss Bridge
A Howe truss, on the other hand, is best for short bridges. Popsicle sticks are a fantastic building material because they are super cheap. However, we discovered that they aren’t quite long enough to make this bridge work. I used 6 sticks and some hot glue to create longer sections. Like all mechanical, civil, and aerospace engineers, I learned how to analyze structures early in my engineering education.
Then decide the number of sticks you will need to build it. You’ll also want a strong pair of shears to cut some of the sticks. Go back with the hot glue and apply some to all the points that had been glued done previously. One particular weakness was taken into account. Make sure to have a spacious and flat working surface.
Kids can build a strong popsicle stick bridge using colored popsicle sticks and school glue to glue sticks.. It is a simple way to teach about how important structure is to strength. To make an arch bridge using popsicle sticks, you will need to follow certain steps. Firstly, create a blueprint or design of the bridge.
