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. This is soo cool. I’m doing a school project and I have to build a model bridge. This helped me a ton!!! Thanx soo much!

    • Lainie, this is specific type of arch bridge called a camelback arch. The difference is that the arch on this bridge is not continuous. Instead it is broken up into sections, and those individual sections are straight. Does that make sense?

    • yes it is u can look up on the internet too and see it or just type in how to make a span bridge out of popsicle sticks and this wesite will be near top of page

  2. How do you determine the efficiency of the bridges, and based on their scores what would the scale be?

    Thanks in advance

  3. How would you test for the mass the bridge can hold? the top of the bridge is not straight so you cannot place books/weights on top

  4. is this the design that you currently have a license for selling because this would be something very fun to build during a weekend just to get better at bulding bridges.

  5. Mad man serz!!
    Helpz me out big time
    One question??

  7. Thank you so much Garret for posting this online! You’ve given me hope keep on living my bridge-building life! We are having this competition on my physics class at school and I think with your design I might just win!

    • Hi!

      My partner and I have a physics project due in a couple weeks, and we are drawing a major blank on even where to begin. We cannot decide on what kind of bridge. Therefore, I am grateful for this website. I think it will help alot, so thank you. I do have a question though… What kind of glue should we use? And could you possibly tell or give a hint on what kind of bridge would be the best to use. Because our teacher is going to place a mass of about 40g in the middle. From it, there will be a hook hanging below the bridge with a bucket hanging on it. My teacher will then proceed to load sand into the bucket until the bridge breaks. Hopefully, that’ll give you an idea on what kind of bridge is best. Get back to me asap. Please and thank you!
