How do Boy Scouts create campfires?
And I don't mean by rubbing two sticks together.
They sometimes use rocks instead of sticks.
Special kinds of rocks.
Like flint and steel.
You'll need both.
Where can I find flint?
Where can I find steel?
How can you create a spark with flint and steel?
It shouldn't strike you odd...
To strike them together.
Use the flint with the steel near the gunpowder placed on the dam to create an explosion.
