Make mini flamethrowers, exploding fireballs, and flint bomb sparklers! Here's how you can modify disposable lighters into small scale pyrotechnics! Mini Flamethrower: By hacking into the valve tensioner and adjusting it counter clockwise, you can shoot a flame 12 inches long! Spark-Making Flint Bomb: Taking the striker wheel off and removing the flint and spring is the next step toward making a flint bomb. The flint is spring-loaded and will fly out under pressure as soon as the wheel is removed, so be ready to catch it, or prepare for a scavenger hunt to recover it! Wrap the flint into the spring so it holds securely, and now you can hold it in an open flame for about 25 seconds until it glows bright orange. Throw it at the ground with force and watch the sparks fly! Exploding Balls of Flames: With the leftover lighter bodies still full of liquid butane, you can try smashing them down on the ground next to an open flame... For me, this resulted in a giant flaming fireball. Probably not the safest activity, but a lot of fun since nobody got hurt this time.
