Working Principle of Popsicle Bridge :

When the bridge is built, potential energy gets stored. Higher the bridge, higher is the potential energy accumulated. When one popsicle is removed from the structure the entire structure collapses converting the stored potential energy to kinetic.

When each unit is joined, it gets interlocked and the structure stands without any binding agent.  When one popsicle is removed, the interlocking breaks and the entire structure collapses.
