Xerxes' Pontoon Bridge Plank

Origin
Xerxes the Great was the fourth of the king of the kings of the Achaemenid Empire. He ruled from 486 BC until his murder in 465 BC. He conquered large areas of mainland Greece. During one attempt, he told architects to construct a bridge going from Asia into Thrace across the Hellespont Strait. When that bridge collapsed from a storm, he had the builders beheaded. Instead, he constructed a large bridge made from tying together over 360 pontoons together using ropes made of white flax and papyrus, tightened with winches and anchors on each side.

Usage
When placed in a body of water the plank will recreate Xerxes' pontoon bridge from one side to the other. This will allow many people to cross the river, but it will not support the weight of a car. To deactivate, rip out the glowing plank from the first pontoon. The remaining pontoons will disappear instantly.
