Step 1: Materials
-An empty Bic or similar lighter
-A pair of scissors
-A tissue paper
-A pointy object
Step 2: Preparing the casing
Now, carefully remove the spark wheel, the flint and the flint spring (Picture #2). Watch out because the spring can easily fly out with the flint and if you lose either the spring or flint your project won't work.
Your lighter should now look like picture #3.
Next, squeeze the red gas switch out with your pliers (Picture #4), and remove the little plate under it as well and the spring that holds the gas switch in place (Picture #5).
Now, with your pliers, remove the pin located halfway in the fuel casing, halfway out (Picture #6). Your lighter should look like on picture #7.
Finally, with a sharp object, push the interior metal pin, that was holding the one you just removed, inside the fuel casing. You have now a prepared lighter casing!
