Picture of A Homemade Whistle in less than a Minute
In this Instructable I will show you how to make a quick whistle from a tin can.

When I was a kid we used to make these whistles out of jam tin lids. 

Apart from being a fun toy for kids, I think these whistles would be great working with dogs, directing cranes, or even to attract attention in an emergency. They are pretty loud and you don't have stick your fingers in your mouth - this can be a pain if you happen to be wearing gloves or your hands are dirty.
I have heard that similar whistles are popular with shepherds in New Zealand who use them for directing their dogs.

Step 1: What you will need

Picture of What you will need
1 lid from a tin can
duct tape

A drill with a bit about 3mm
hammer and centre punch
A small piece of ply or something to bend the tin around. About 4mm thick.
A knife for cutting the duct tape.

I liked this whistle except for putting the metal lid in my mouth.
I finally tried an old credit card or hotel key. It wasn't quite as durable but easier to make and no unpleasant metal taste.
I even made one in a hotel room with the hairdryer to bend the plastic.

If I don't have a drill, what do I use? Just the nail? Please reply..

You could try a nail. It depends on the thickness of the material. Good luck.
Cool! Great instructions! It didn't take long, and was very satisfying in the end! Thanks!

if i made the hole smaller would this work as a dog whistle?

I haven't tried it. Give it a go and let me know how it is.
he means would it work as a silent dog whistle
It works as a dog whistle "as is" - this is what shepherds use to signal their dogs on the far side of a field.

hey i made one but it doesnt sound? tell me your secret? ;)

It does take a bit of trial and error to figure out how to make it whistle, but once you get the technique it's easy.
I tried to explain how in the last part of the ible. But it's not easy to communicate in words.
Good luck.

The whistle seems to get warmer or colder as you play it. Convection cooling and heating? Neat!

I use to make these out of flattened pop bottle caps.
