This is a shot of a highlighter right at its moment of explosion in a microwave. It kind of looks like cotton candy. Why would anybody put a highlighter in a microwave? Keep in mind this was a 4th of July weekend and not everyone can afford fireworks. "Sooo...." Yep -- you're looking at a redneck sparkler, bro.
Thanks to PYY, who can't believe there isn't some sort of age restriction on being able to buy microwaves.
