Anyone who ever set fire to ants using a magnifying glass: first of all, shame on you! Second of all, you're going to love this. Sunlight, focused intensely enough that it can (and does) burn any material on earth.

Just how hot does it get in that ring of fire sunshine? Over 6,300 degrees Fahrenheit. Which should be hot enough to handle business when the mutant mega-ants stage their inevitable uprising. [BBC via The Daily What]
