You have two agarbattis on a boat

You have two agarbattis on a boat but no source of fire. How will you light an agarbattis if you are in the middle of the river?"

Some answers are:

1) Throw an agarbatti into the river. It make the boat lighter. Use it to light agarbatti

2) Throw an agarbatti in air and catch it. Catches win matches. Use these matches to light agarbatti

3) Take some river water, let it fall drop by drop. You know that "Tip-tip barsa pani, pani ne aag lagai.". Use it to light the agarbatti.
