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.

Build This Bridge

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.

  1. 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?

  2. Wonderful! Can you give me the process of making a bridge especially the connection and distribution of loads. Big thanks.

  3. Suggestion to the builder of the bridges: The joints failed, and it appears that they could use a vertical stick on each side of them to brace the sticks, an x-shape the way the glue holds and the way it works will have each stick of the x slide a different direction.
    brace the joints by gluing vertical and horizontal bars to each side.

    • im not sure wat glue they used but i can recommend the ad tech multi temp glue gun glue much better than glue sticks/glue bottles,tacky glue and all that other stuff if any to tell u the truth is really good glue and if u get it on u u only fell a slit sting of heat but it dont burn ur skin or nuthin like that
