Signaling is one of the most important things in survival signaling for help getting rescued unfortunately humans throw trash everywhere but that could benefit a survivor i'm going to show you how to make a whistle from a soda can so we're going to do is we're going to take our multi-tool and we're going to cut about a half inch over.

In about two and a half inches strip of a can then we're going to cut another half inch by an inch now we're going to take the smaller piece and place on top kind of like a t and fold under we need to make sure we have a little gap here and you can shove a stick or something in there just to bend it up and just bend.

This up because this will be actually the mouthpiece now we're going to fold the can in a manner that is a shape of a whistle we're going to use our thumb and index finger to make the sides of the whistle
