Ladies and gentlemen, this is how they do it. This is how they ignite the Olympic torch, match- and lighter-free. This is also how you can start lighting your campfires, cigarettes, cigars, incense cones, and in the great states of Colorado and Washington, big fat fatty joints.
The Solar Spark lighter and fire starter is a pocket-sized parabolic mirror able to catch and focus the sun's radiant energy right into the heart of its metal coils. To activate, just point the Solar Spark disc towards the sun, scream "I summon the breath of Ra!" as loud as you can, hope Ra is in good spirits and not all moody and emo like he was in Stargate, and watch your flammable item catch fire in seconds.
Of note: the lone reviewer of this particular multi-purpose igniter of useful things comments that while the model does work as advertised, it merits only 2 out of 5 stars because it is cheaply made. However, I would point out that it's also pretty cheaply priced. Those interested in a seemingly sturdier and possibly longer-lasting Solar Spark lighter might prefer to roast their marshmallows on this stainless steel version of the gadget.
