Step 1: Equipment
- 2x Bottle Caps
- 1x length of string (around 5 cm)
- 1x a small bundle of tinder ( For this i am using silver birch bark
- 1x small portion of super glue if wanted (not required)
Step 2: Primary Cap prep
Then start pushing the outer circle (the bit that grips the lip of the bottle) inwards this is the fiddly bit because it needs to be able to fit snugly inside the second unaltered (once of the bottle) bottle cap, It should create a friction fit to the second Cap but before you lock the two in place you need to do the next step.
Step 3: Tying up loose ends
Now tie a knot in each end and place both ends next to each other in the bottom of the Marked Bottle Cap on top of which you will place your tinder.
