This principle is derived from the laws of physics, which state that weight can be dissipated and transferred efficiently through the curves, resulting in more stability. Therefore, no single point bears too much weight, which means that the bridge is less likely to collapse. Begin by taping 7 gusset plates to your work surface as shown.
Supplies Needed for Popsicle Stick Bridge Design
This caused those angled popsicle sticks to twist, and the bottom chord starts to twist a little as well. I think it was a glue joint that came loose and started the chain reaction. The angled sticks on the ends may not have been perfectly even and square with each other, which would have caused a weaker joint. First I added some cross beams (four cross beams).
DIY Miniature Bridge How To Make Popsicle Stick Bridge
Younger kids will be impressed by how they are built and older kids will have a blast building them. In less than 5 minutes, kids will be able to build their own bridge using hot glue guns and popsicle sticks. This activity is more suitable for older kids with the supervision of an adult, but younger kids can watch and learn about bridges. Now you are ready to build your popsicle stick bridge.
Popsicle Stick Bridge Projects Kids Can Build
I only used a level 1 sort for these popsicle sticks, so this is possible. I connected the two sides by placing popsicle sticks across the two sides with glue. There was one problem, I should have measured the popsicle sticks before I glued them because I still had a little bit hanging off the side. Balsa wood is not considered strong as it is a soft wood and thin pieces of it break easily. However, it has a good strength-to-weight ratio, making it suitable for building lightweight structures...
It was not something I put a tremendous amount of effort into, just a quick and dirty design to show the concept. Behind me, you can see an image from the computer program I used to model and design the bridge. The Pratt truss bridge works through tension (stretching something) and compression (squeezing something together). In very basic terms, the Pratt truss is a series of triangles that help distribute the load across the structure. The diagonals of the triangles all slope toward the center, except for the two diagonals on the outsides.
Applications Of Arch Popsicle Stick Bridge
Truss bridges are made up of a series of interconnected triangles, which provide stability and strength. To make a truss bridge out of popsicle sticks, you will need to create a series of triangles using the sticks, and then connect them together to form a bridge deck. The key to making a strong truss bridge is to ensure that each triangle is properly aligned and securely connected to the surrounding triangles. Build an arch bridge with popsicle sticks by using the effective triangular design. Ensure the sticks are arranged in such a way that none of them can rotate, making an unbreakable truss.

Every arch bridge has unique characteristics that distinguish it from other bridges. However, there are basic components that are common in all arch bridges. These include the abutments, which are the supports that bear the load of the bridge. The keystone, or central stone, is placed as the last piece in the arch and locks all the other stones in place.

Stick Popsicle Bridge: 21″ Howe Truss
Weave sticks 8 & 9 (red sticks) under the orange stick and on top of the green stick. If you slowly let go of your bridge after you get these sticks into place, if will raise itself up so that the red sticks make a platform parallel to the ground. You can stop here or keep going to make your bridge longer... Take this project a step further to see how much weight it will hold. Figure out the dimensions of the bridge you want to build.
Repeat with the next set of angled supports, with the bottom of the popsicle stick touching the bottom of the innermost vertical beam of that set. The Pratt truss is made by a simple web arrangement of diagonal beams (or sticks in our case) in tension and vertical beams in compression. Kids of all ages will have fun with this craft stick bridge STEM challenge.
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. I also added more supports were it looked week. I noticed that some popsicle sticks had some gaps between them. So I decided to fill in the gaps by cutting some popsicle sticks up to the right size and putting them in there and sealing it with glue.
If you wish, attach an extra craft stick at those points for reinforcement. For this step, I added supports along the top and bottom of the structure to connect the two sides we made in Step 3-6. Finally, add an angled support to the outside on each end. In this case, the angle will be the opposite of those inside, since you’re forced to angle it a certain way because the bottom beam is longer than the top beam. First, place the bottom piece and top piece on the table, the length of a popsicle stick apart, and try to line up the midpoint of each as well as you can.
