My first bridge for the science olympiad

Hi this is Hyun Seok Yoon. As the title says, I just made my first bridge for Science Olympiad! Although it took me 12 hours (whew..!) I could see the good result! It held 15kg!

Popsicle Stick Bridge Videos

Here is a video playlist I created from youtube of selected popsicle bridge movies. You can see a variety of testing methods used in these videos. You can also see a lot of people not wearing eye protection, which is not a good idea. Always wear eye protection when testing a bridge.

Ryerson I-beamers’ 2009 Popsicle Bridge

This is a video I found on YouTube of an excellent bridge built for the Troitsky Bridge Building Competition. The only materials allowed for this competition are popsicle sticks, toothpicks, dental floss, and white glue. This is a very impressive bridge. It weighed 1.17kg and held 805kg.

The presentation is over an hour long. He shows how to build a bridge from scratch. He is gearing his video towards the…

Video: Tips on Building Popsicle Bridges

Here is a video from youtube that is a young man giving advice on building popsicle stick bridges after building one of his own. I like his thought process although I don’t necessarily agree with everything he says. What do you think? Notice when he says he sacrificed making triangles to add beauty to the bridge. Do you think this was acceptable? What would you have done?

World’s Longest Popsicle Stick Bridge

Here is the story of the Prairie Popsicle Stick Bridge told in video format. As far as I know, this is the longest working popsicle stick bridge that a person can walk across. If you know of a longer bridge that does the same, please let me know. The largest popsicle bridge was built back in 2008 in my dorm room at Prairie Bible College. For many nights I slept on the floor, as I was using my bed space as a worktable to glue the bridge together.
