Those of us who have reached a certain age probably remember the TV series "MacGyver." With ridiculous plots and exotic locations, that weekly dose of escapism was enhanced by knowing that no matter what deadly scenario the eponymous character found himself facing, he'd solve his problems and save the day by turning a few found items into a plot device. The show was so well known for this gimmick that the concept of making a useful tool out of things you found lying around became known as "MacGyvering." Grant Thompson, also known as The King of Random, clearly worships at the altar of MacGyver. One of his classic hacks channels the spirit of this improvisational hero by taking a simple chewing gum wrapper and a double-A battery and turning them into a tool that just might save your life. Or at least save you some hassle.
