Just a quick link to a post on Lifehacker that links to another blog about how to waterproof matches.
A useful thing to know how to do.
UPDATE: here is another post I came across on Lifehacker that is apparently from an old Backpacker issue which tells how to use your coffee as a barometer! Read the story here.
Hmm – I couldn’t get either of the links to work.

(Wotcha! by the way…)
Nor could I.
The first one did change colour nicely though!
Thanks for the heads up. I forgot to test the links!!! Noob error there
