Survival Whistle from a Soup Can

I want to show you an awesome survival hack by turning a soup can in to an emergency whistle.

Watch the Video:

Let’s imagine you are hiking or camping and you become lost.

That can be a scary situation.

Here is a great way to signal for help.

What you Need:

- Metal can (soup can)

- Large nail (small screwdriver or rounded tool)

- Medium sized rock (for hammering)

- Flat hard surface (rock or concrete)

Use of content for personal projects is at your own risk.

This project was inspired by "cammers" and his instructable can be found at:


Step 1: Removing the Lid

Removing the Lid

Start looking around for a thin piece of metal.

In this case, a tin can or soup can would be perfect.

The first thing we need to do is remove one end of the can.

A can opener would be best, but if you do not have one, then a large flat rock or some concrete to remove the lid.

Most cans have rolled edge to seal them.

So place it face down and drag it back and forth to grind off the edge.

This may take a couple of minutes but it will work.

*Caution* - The edges will be sharp.

Step 2: Shaping the Lid

Shaping the Lid

Now carefully fold the lid in half.

We now need to puncture a small round hole through both sides of the lid.

You can use a large nail, a small screwdriver, or maybe even something on your Swiss Army knife.

Next find a large rock to assist you.

Now place the nail about 1 centimeter inward from the folded edge and hammer a hole through both sides of the lid.

After removing the nail, one side will have a sharp jagged edge where you made the hole.

Carefully bend down these edges if you can, so you won’t cut your mouth.

Now pry open the lid to about a 30 degree angle. This will help create the sound.

Step 3: How to Use It

How to use it

To use the whistle, carefully place your tongue on the folded edge with the jagged hole side facing upward.

Make a tight seal with your lips completely surrounding both holes because all of the air must flow through them.

This design is very similar to a sheep dog whistle and may take a little practice to get the loudest sound possible.

But I can tell you from experience that you can and will annoy your family with it.

So there is a great way to turn a soup can into a survival whistle.

**And if you happen to find a can with a peeling lid, the tab makes a great handle.**
