A Warren Truss bridge is made with equilateral triangles that divide out the weight on the bridge. This makes the bridge really strong. To start, you will need two rows of popsicle sticks for the bottom base. Start by lining up three popsicle sticks end to end. Glue on two overlapping the seams. Then cut one stick in half for the two ends.
How to make miniature bridge from popsicle sticks?
- Multiply the width of your truss measurement by two to account for the width of both trusses and then add the width of the deck.
- Cut three or four popsicle sticks to this length.
- If your popsicle sticks are too short, make a longer one. Cut two sticks and, with glue, join each by attaching another stick to the bottom for support.

What is the strongest type of bridge?
Even though the truss bridge design has been around for literally centuries it is widely regarded as the strongest type of bridge.
What makes bridges so strong?
Suspension bridges are strong because the force on the bridge gets spread out. The weight of the cars or trains or horses, whatever's traveling across it, pulls on the cables, creating tension. Those cables then pull down on the towers and also pull on the anchors on either end of the bridge, to hold up the deck.

What is the easiest bridge to build?
A beam or "girder" bridge is the simplest and most inexpensive kind of bridge. According to Craig Finley of Finley/McNary Engineering, "they're basically the vanillas of the bridge world." In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers.

What is a Warren bridge?
1) The bridge is built with cast iron side bands, rods, or plates, inclined towards each other, and combined so as to form a series of Vandykes [V shapes]. They are bolted at top to horizontal compression rods, and at bottom to horizontal tension rods, and carry a roadway at top or at bottom, or at both.
What is the difference between a triangle and a popsicle stick?
Be sure to incorporate lots of triangles into your bridge design. More popsicle sticks doesn't necessarily mean a stronger bridge.
Why is it important to clamp a popsicle stick?
Clamps are important because most of the popsicle stick aren't flat, so if you don't clamp them when you glue them together your bridge probably won't hold together very well. Don't pinch your fingers. Keep your workspace clean! I glued everything on top of a piece of paper, as I have a tendency to get glue everywhere.
What glue do you need to make a popsicle bridge?
All you need to make this popsicle stick bridge is a good strong glue and some popsicle sticks. This Elmer’s X-Treme glue worked like a miracle! Wood glue also works great here.

What is bridge building?
Bridge building is a great STEM engineering project for students. It is a simple way to teach about how important structure is to strength. You can build a bridge many different ways, and they will not all be equal. Take this bridge building project a step further by competing with other bridges to see which one hold up the most weight.
Is a popsicle stick bridge strong?

How to build a bridge with popsicle sticks?
1. Lay out the deck of your bridge. Set your two trusses flat on your workspace so that each lay parallel. Then, take your popsi cle sticks, laying several crosswise between each of your trusses. These will form the deck, or the road, that runs the length of your bridge between the truss walls.
How to make a truss with popsicle sticks?
To lay out your truss: Lay out four rows of popsicle sticks with each row being three sticks wide . Each row should be equal in length. Cut four popsicle sticks in half. Place each of the halved popsicle sticks at both ends of each of the truss beams, in the middle position of the three-wide popsicle sticks.
What determines the width of a bridge deck?
The distance between your crosswise popsicle stick deck will determine the width of your bridge deck.
What is the process of putting popsicle sticks together called?
When layering sticks together, a process sometimes called "lamination, " you can achieve better strength by staggering your popsicle sticks.
How long does it take for glue to dry on a truss?
Other kinds of glue, like wood glue or general purpose glue, should be allowed to rest 10 to 15 minutes.
How to measure the width of a bridge?
Lay your yardstick crosswise to note the width of your bridge.
What is a blueprint for a truss bridge?
Imagine a blueprint for your bridge. A blueprint is a drawing that will serve as a plan for your design. Truss bridges can varying degrees of complexity, and you should investigate a few designs on your own before coming up with your design. Generally, a truss bridge has: Crosswise floor beams and struts.
How to make a bridge out of popsicle sticks?
Create the top and bottom cords for the bridge by laminating Popsicle sticks. Spread glue on the flat side of one Popsicle stick. Place a second stick halfway down the Popsicle stick, and another Popsicle stick on the other half. Use a binder clip to clamp the sticks in place while the glue dries. Continue gluing the Popsicle sticks in this pattern until they reach the desired length of the bridge. Be sure the cord is completely straight and even as the glue dries – curves or wobbles will reduce the bridge strength. Repeat until there are four cords, two top cords and two bottom cords. Allow the glue to dry completely.
What is a popsicle bridge?
Building a bridge out of Popsicle sticks is a great way to learn engineering and architectural principals. While there are many types of bridge designs to choose from, a truss bridge is a good one to begin with. Truss bridges – bridges that are a combination of triangles – combine strengthening techniques such as laminating and bracing. Popsicle sticks are glued together to make strong cords, braces are added, and finally the deck of the bridge is laid in place. Plain white craft glue, Popsicle sticks and binder clips are the only supplies needed for this type of bridge.
How to rotate popsicle sticks?
Hold one end of each popsicle stick in each hand. Gently try to twist them back and forth, rotating about the joint where they are connected by the binder clip. (Do this by sliding the flat surfaces of the popsicle sticks against one another, do not try to "break" them by bending them.) How easy is it to rotate the popsicle sticks about the joint?
How to prevent a truss from rotating?
The only way to prevent the square from rotating at all is to pinch down very, very hard at the joints (imagine using much stronger binder clips). You can now see why it would not be good to only use squares when building structures—all of the joints would have to be superstrong! The triangle, however, has zero degrees of freedom—all of its popsicle sticks are fixed in place and cannot rotate. This means you can build a truss structure out of triangles that does not rotate or deform—even though the joints are only lightly held together by binder clips.
Can you use K'nex to make trusses?
Extra: If you have building toys available, such as K'nex, Tinkertoys or LEGO Technic pieces, try using them to make trusses of different geometric shapes. (Note that this will not work with regular LEGO bricks, you need beams with holes that can be connected by pegs.) Do you get the same results as you did with popsicle sticks?
Do popsicle sticks move?
When you try to rotate the popsicle sticks in the triangle-shaped truss, however, they do not move. The triangle design is "stronger"—the popsicle sticks are arranged in such a way in this shape that when you push or pull on them, none of them can rotate.
