Douse them with water. Bury them in earth. Blast them with air. None of it's going to stop these matches from burning. And I'm assuming Heart wouldn't put up much of a fight against them either.
You can get two packs of 25 of these REI Storm Proof matches for just $5.50. The 2.75-inch wonders are definitely impressive, until you realize that even if you can get the matches to light in those conditions, whatever fire you start with them is pretty much doomed. [REI via Geekologie]
