We go a tiny Engineering project this past week in ours house and built a popsicle stick bridge. It to be a yes, really fun project to perform with the kids. We used colored popsicle sticks and Elmer’s X-Treme school Glue to make the bridges watch cool and stay STRONG!

(This is a sponsored write-up in instead of of Elmer’s. Ns am gift compensated for my time in writing this post.)

Want a much easier bridge without glue? Try this one!

Bridge building is a good STEM design project because that students. The is a simple means to teach around how essential structure is come strength. Friend can develop a bridge countless different ways, and also they will certainly not every be equal. Take it this bridge structure project a step additional by completing with other bridges to check out which one host up the most weight.

Yes, ours popsicle bridge is messy and crooked, however my kids had a blast do it and also it is strong!

All you have to make this popsicle stick leg is a great strong glue and some popsicle sticks. This Elmer’s X-Treme glue operated like a miracle! wood glue also works good here.

How to construct a Popsicle rod Bridge:

When structure the bridge, you should start with your bridge design. We made decision to make a truss bridge through our sticks. A Warren Truss leg is made with equilateral triangles that divide out the load on the bridge. This renders the leg really strong.

To start, girlfriend will need two rows of popsicle sticks because that the bottom base. Begin by lining up three popsicle sticks end to end. Glue on 2 overlapping the seams. Then cut one rod in half for the 2 ends.

Repeat this three more times.

You will certainly then make two much more with just two popsicle rod making much shorter beams. These space going to do the trusses. Making use of a 3-stick beam and a 2-stick beam that has mostly dried, connect them v the sticks making a triangle pattern.

Once that dries a for around 15 minutes, flip it over and also repeat the triangular pattern on the various other side to make it twin thick. You will certainly repeat this to make the 2 trusses for the political parties of the bridge.

*

The various other three-stick beams room to be supplied as the bottom base of the bridge. Place them parallel to each other and also glue sticks going across the bottom connecting them. This would be the road that the vehicle would drive over if it were a really bridge.

*

Once the basic is done, adhesive the side trusses top top standing follow me the edge. Ns glued it and propped up some books along the next to hold them increase while they dried. Affix the sides with each other along the peak with another triangular pattern.

Ours ended up pretty lopsided, but it still hosted together amazingly well! My daughter to fill in the uneven parts along the bottom through some extra pole to store it balanced. She was SO proud of her creation!

I think this may be the strongest Popsicle Stick leg out there!
