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.

Here is my sister standing on the bridge:

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.

Here are some photos of the broken bridge. 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.
