Olsson Engineers Tackle High‑Energy Mystery Box Challenge for Engineers Week 2026

To celebrate Engineers Week 2026, Olsson employees put their engineering skills to work through a friendly competition—a Mystery Box Challenge. Employees received a surprise mystery box of supplies and instructions. The challenge was fast-paced and complex. Teams were expected to build an innovative catapult to launch a bean bag with power and accuracy. One team claimed the coveted firm-wide Engineers Week trophy.
