For the second step you will want to cut 2 pieces from the foil.

on one cut will be going long way with the can the cut should be about as wide as the tab from the pop can

the other cut will be a box about the size of two tabs from the pop can.

Step 3: Making the Inner Part of the Whistle

Fold the wide piece of foil around the long narrow cut and cut the corners of the top.

Fold the top of the long end down and over the fold to hold the wide piece in place.

Step 7: Slice and Dice

you need a stiff,rugged yet flexible piece of tin. That's why soda cans work well for this. On the other hand, if you look at professional whistles you'll see they use a thicker piece of metal that are either soldered or glued together.
