In this project I'll show how to create an extra loud whistle made out of a Wrigleys Extra Mint Container. If you have all the parts, this shouldn't take you more than 30-40 minutes to make. The whistle is extremely lightweight and a great addition to your outdoor adventure or survival kit. The video below doesn't really do the whistle any justice... It's even louder in the fresh.
Step 1: What You Need For The Build
If your lucky you might find all these things lying around the house or garage;
- A empty Extra Mint Container or something similar.
- A good pair of scissors
- 2 1/8" Bolts and 6 matching nuts
- A 1/8" Drill Bit
- A Drill (Battery or Hard Wired)
- A pair of Pilers
- Some Sandpaper, and
- A fine permanent marker pen
Step 2: Cutting Up Your Container
After you've found a suitable tin container for the job, start by marking and cutting out the main 3 pieces that go together to form the whistle; there are 2 pieces 65mm x 13mm, and 1 middle piece that is 72mm x 13mm. This middle piece is a little longer, so you can conveniently attach it to a lanyard, necklace or keychain. All the dimensions are list in the image above. Caution; be careful when cutting out these pieces, as the cut edges and off-cuts can be very sharp.
Step 3: Drilling The Holes
Once you've cut out your 3 main components, ensure each piece is nice and flat. Use your sandpaper to remove an sharp edges. Follow the dimensions in the image plan and mark out each point for the holes. Now using a drill on low speed, carefully drill out each hole using your 1/8" Drill Bit. It's ok if you use a sightly bigger drill bit and/or nuts and bolts, just not too much bigger or your project won't work.
