Building Science Trivia Time

IBS 2024 inspires a homegrown game designed for GBA readers

The BS Boys at IBS 2024, from left to right: Ben Bogie, Jake Bruton, Peter Yost, Steve Baczek, and Tate Hudson

For the past few years, Huber Engineered Wood has held a building science trivia game in their booth at the annual International Builders’ Show. It’s played with a mobile app; contestants answer questions, and their score is based on whether they are right and how quickly they answer. The game is just for fun, though there are some bragging rights if you can beat the onstage contestants. This year, they were Jake Bruton, Steven Baczek, Peter Yost, and Ben Bogie with Tate Hudson from Huber asking the questions. (Jake has this year’s bragging rights.)

Some of these questions are from Huber’s game, others are from a recent BS* + Beer, Northern Minnesota meeting (quick aside: if you want to learn about setting up a local chapter, watch this epsisode of The BS* + Beer Show). Keep track of your answers. The test answers—along with some explanatory information—will follow the quiz. OK, here we go.
