Grolsch Keychain in Under 5 Minutes




In this instructable I will show you how to make a key trinket from a Grolsch bottle cap.

Step 1: Gather the Materials

You will need:

  1. bottle cap
  2. key ring with chain
  3. copper wire or other material
  4. 1mm and 3mm drills
  5. pliers for cutting the wire.

Step 2: Drilling the Bottle Cap

For this step you have to remove the red gasket from the cap.

Drill a hole in the bottom like in image. Make sure the chain can fit in the hole.

Now drill 2 side holes for the wire. It is better if the wire enters hard through the hole.

Step 3: Cutting the Wire

Measure the length of wire needed and cut it.

Step 4: Attaching the Chain

With the last link of the chain in the hole push the wire all the way through the cap so it locks the chain in place.

Step 5: Finishing Touch

Put the gasket back on and you're done. Your cute keychain is finished.
