Real World Problems
Building toothpick bridge are greatly related to real world problems. The world needs bridges to connect one location to another ( example: a valley, river, roads, etc). If a bridge fails to support a certain amount of weight, then it might break. If people are on the bridge when it breaks, it could be disastrous. That is why toothpick bridges can be used to guess how the real bridge will react if it holds a certain amount of weight. Engineers can use this information to build real bridges. They could've used toothpick bridges as a prototype for the real thing. Testing a prototype first is safer than testing a real bridge.
