What do you do when you have an outdated / older edition iPhone, a 65" Fresnel lens, and apparently nothing else better to do in your free time? Why, toast your iPhone, of course.
There are some people out there who take their iPhones seriously. They get EVERY EDITION of the iPhone that comes out, in the same way your local comic book guy might avail of every single cover design X-Men #1. Every purchase of a new iPhone makes the previous one obsolete, ensuring that their owners dispose of them in a variety of ways.
One way apparently, is by death ray. Using a 65 inch Fresnel lens, some batteries, and a large backyard, one consumer proves that old iPhones can still sizzle - literally.
