1. Use the scissors, if necessary, to cut off the non-burning handle of each stick, so that you may light both ends.
2. Light three of the four ends at the same time.
3. The stick with both ends lit will burn out in 30 minutes. At that time, light the other end of the other stick.
4. In 15 more minutes, the other stick will burn out, for a total of 45 minutes.
