Slow Mo Guys Go Gruesome With Close Up of Bug Zapper

I remember back in the day playing Tennis with the old wooden rackets. It being out doors, the bugs would be plentiful, and we would swing the racket through the swarm to see how many we could kill. If I had a brain for business I could've invented the Bug Zapper that looks like a tennis racket. Ever wonder how it works? The Slow Mo Guys went to work recording the death of flies. Kind of gruesome, but cool.
