For camping: Prep some firestarters. Fill an egg carton with dryer lint and pour melted candles into each cup, let cool. Tear them off and ignite to start a quick fire. I have been looking for something to do with all that dryer lint!
*Bridget did this with individual egg-bubbles. I think that a whole one, or even cutting into thirds would be an even more better fires starter (for woodstoves). Egg crate + dryer lint + melted wax = fire starter (think camping or backyard fire pit)
