Yesterday we showed you how to make a survival lantern from a soda can. Since there are A LOT of things you can do with a soda can we're going to keep up the trend and show you how to make a survival whistle from a 12 ounce can.
Step 1 - Cut out a small square from your can.
Step 2 - Now cut two strips. A 2 inch strip and a 1 inch strip.
Step 3 - Make a cross out of the two strips.
Step 4 - Fold the two flaps of the cross in.
Step 5 - Use a Multitool or knife to create separation between the two pieces of foil.
Step 6 - Fold the top over into an L shape.
Step 7 - Now bend the bottom piece up so you create a small circle.
Step 8 - Use your thumb and forefinger to close off where the air can escape from the sides.
Step 9 - Adjust the width of the opening until you have your whistle dialed in.
