I have read many books on survival and I have seen a cylinder that is used to compress the tinder untill the tempature reaches so hot it explodes into a small flaming part. Then you just remove that from the cylinder and it replaces the need for matches and it last for ever. I think this would be awesome has anyone ever made one or bought one. I also think it it was the right size then you would be able to put matches in it to double as a match case. Thanks a lot.<br><br>snow day yeeehaaa
