Introduction: Loud, Easy, Simple Whistle (Bic Pen)
This is a great whistle very similar to many whistles available from places like REI or Eastern Mountain Sports. Its is compact, since rather than using a cork ball, it simply uses air. It is cheap and only requires a bic pen. It also makes a great addition to survival kits, such as the Altoid Survival Kits found on Instructables. (See link.) This is my first instructable, so I decided to start with something simple. Please drop me a comment.

(Note: This is a very loud whistle and a knife is used to make it. I am not responsible for any injury caused by using this whistle)

Step 1: Materials and Tools
You will only need a bic pen and small knife.
Step 2: Preparing the Body
Remove the front section from the pen, including the tapering plastic piece and ink tube. Leave the main body as well as back cap. Using your scissors or knife, cut about an 1 3/8 inch section of the back of the pen including the cap on the back.
Step 3: Using the Whistle
To make the loudest sound, try pressing the rim of the whistle into the ridge of your lower lip, where the wet part meets the dry part. Then put your upper lip slightly above the rim of the whistle and tilt the bottom of the whistle slightly outward. Adjust as necessary.
