Bridge Building - The Testing Phase

All bridges passed the three tests: 

• Two Hot Wheels type toy cars must be able to pass each other
• Must support two weights of 200g each
• Must withstand the "wind test"

All Bridges were less than 50 cm long and were completed on schedule. Six out of nine were long enough to bridge the 30 cm gap. Four bridges were built "under budget", using either less than 40 straws, less than 2 m masking tape, or both. 

Well done engineers!
