Step 1: Materials
Opional stuff that makes the project easier, but not necessary-
Knife (more fun than scissors)
Step 2: Cut! or Tear!
Step 3: Wrap!
Make sure to wrap in such a way that the aluminum foil completely seals off the two portions of the match- if you don't, the flame will just keep on burning....
Step 4: Light!
You've created a disposable guard for any size match. Soon, It'll take about 5 seconds to do the entire project, from start to end. :D
*To make a perfect line if tearing, crease the foil along a table edge first.
