Elida, Ohio -
This may be how some of the great engineers of the world started their long careers.
Physics students at Elida High School are literally learning how to build bridges.
Each student is given a specific amount of Balsa wood and strict guidelines on how the bridge can be built.
A big chunk of their grade in the class depends on whether the thin timbers can shudder and shake long enough to hold at least 35 pounds.
Most hit the mark but the tension leading up to the weigh-in is always nerve-racking.
The students built the bridges as the culmination of several weeks of studying mechanics including the impact of stress and strain on structures.
