Measure the length you want your bridge to span, then measure the width of one of your tetrahedrons. Divide the length of the bridge by the width of a tetrahedron to determine how many tetrahedrons you will need to make. Step 3 Connect your tetrahedrons together with toothpicks. You can ex...

Building a bridge out of Popsicle sticks or toothpicks is a common project for a beginning physics class. The point of this exercise is to demonstrate distribution of force, capacity, resilience, strength and basic principles of engineering. The key to building a really strong Popsicle stick brid...
