Fire on the island

Fire on the island

We are in the center of an island of approximately 5km radius and completely covered with vegetation. A fire starts at one end of the island that advances at high speed due to the strong wind. So much so that even if we ran in the opposite direction to the fire it would reach us before leaving the island. After checking our backpack we found a canteen full of water, a lighter and scissors.

What can we do to save ourselves?

Solution

We have to cause a fire in the position we are in. Due to the wind, this new fire will also advance at great speed in the same direction as the initial fire so we can walk over the area already burned by the fire we have caused before the fire that originated at the end of the island.
