Give Your Match a Raincoat
To prevent matches from absorbing moisture, waterproof them using hot wax. You’ll need a candle, a glass jar, and a small cooking pot.
Step 1: Cut four 1-inch-thick pieces from the base of a candle and drop them into the jar.
Step 2: Place the jar in a pot of water and simmer until the wax melts.
Step 3: Dip the matches (headfirst) into the liquid wax and roll them with your fingers. Coat about half the length of each match with wax. Let dry and store in an airtight container.
