How To: Make a super loud whistle with a Sharpie marker

This is a simple way to achieve one of the loudest whistles ever! Anyone can learn and it only requires a Sharpie permanent marker cap. WARNING: turn your speakers down because it could be very loud. Try it yourself, and you will find that the whistle is actually much louder in person than on video!
