How can you make sure to start a fire with two sticks?

To start a fire with two sticks, you can use the bow drill method, which involves a spindle (the flexible stick), a fireboard (the base), and a bow to create friction. First, carve a notch in the fireboard and place the spindle in it. Then, wrap the spindle with the bowstring and move the bow back and forth to spin the spindle rapidly against the fireboard, generating heat and eventually creating an ember. Once you have an ember, transfer it to a tinder bundle and gently blow on it to ignite a flame.
