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.

 

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)
