Popsicle Bridge #2
This popsicle bridge was made from 58 unmodified popsicle sticks. It was 25 inches long, 4 inches tall, and 3 inches wide. I used only Elmer’s white glue to build the bridge. It weighed 86.5 grams, and held 45 pounds. Its efficiency score was 248.
I redesigned this bridge from the earlier version. The new one is more efficient. It is also easier to build. I changed the position of only a couple popsicle sticks, and actually took off a few. I found that the average popsicle stick weighed 1.49 grams.
Stronger Version
This bridge uses the same basic design as the one above but doubles the number popsicle sticks in strategic places.
This popsicle bridge was made from 84 unmodified popsicle sticks. It spanned 24 inches, was 4 inches tall and 3 inches wide. I used only Elmer’s white glue to build the bridge. It weighed 118 grams, and held 115 pounds. Its efficiency score was 442.
This bridge is slightly crooked, even though you cannot tell it from this photo. I’m sure that had an affect on its performance. However, this bridge was also tested 5 times. Both my sisters stood on it, and one twice before this picture was taken.
I thought I was making a movie when I tested the bridge, but found out afterward that I hadn’t started the camera. Oh well, maybe next time.
None of the popsicle sticks actually broke. Only the joints failed. This is something for me to keep in mind, as it should be very easy to make this bridge a lot stronger.


















I tried doing that, but I tried gluing seprate triangles together. I’l see how it turns out
i need to find a broken arch bridge
this really helped me in my project for school
-great job. This helped me put a lot while doing my science project.
Hey great job
its going to help me a lot in my project for physics.
I am doing this as a project in my classroom, what kind of scale would you suggest I use to test how much the bridges can hold?
Monica, I suggest using an analog bathroom scale.
