How to make fire starters with old puzzle books
Put some wax into an empty can.
If you have any candles you don't want, these are an ideal source of wax (like the stub of a candle).
Melt the wax in the can.
You could put it on the stove in a pan of hot water, or put it in a slow cooker. Do not just warm the can straight on the top of the stove since that presents a serious fire risk from over-heated wax.
