LED's = 4p each (ebay)

Step 1: Magnet in duck
- Drill a hole the same diameter as the magnetic contact mine required Ø15mm. Place it in the middle of the bottom of the duck. I used a hole saw in a cordless drill.
- You must ensure you use the contact without the wires on.
- The magnet is held in by friction, however if you want a more permanent fixing use hot glue
