On this instructable, I am going to show you how to make a emergecy whistle out of a can!!!

Step 1: Materals

Empty soda can
So the mouthpiece directs air at an edge of the can?<br /> <br /> No sides required?&nbsp; Or &quot;pea&quot;?<br /> <br /> I'd love to hear what your whistle sounds like - maybe a video or MP3?<br /> <br /> <br />
sides are required.&nbsp; Put your fingers on the sides to make it work<br />
&nbsp;you cover the sides with your fingers. &nbsp;its kinda hard to make the angle from the mouth piece to the whole. &nbsp; I would rather say to just learn how to whistle...
When the rescuers find you they'll say 'if only we could've gotten here sooner... before he died from blood loss from his lips'<br />
If you&nbsp;do it right, you wouldn't bleed.&nbsp; Trust me.
