1. Use foam floor tiles for a softer, more comfortable tent floor.
3. Paint the inside of a jar with non-toxic glow-in-the-dark paint for an easy DIY lantern.
See how she did this here.
6. Bring a tick deterrent.
7. Glue sandpaper to the top of your match holder.
Be sure to buy strike-anywhere matches.
9. Make crescent rolls over the campfire.
For maximum yumminess, fill ‘em with stuff like marshmallows and Nutella. Or wrap hot dogs with them.

13. Cut up a straw and fill the pieces up with antibiotic ointment or toothpaste for single-use packets.
Use a lighter to seal up the ends.
14. Make travel coffee bags out of coffee filters and dental floss.
Place a scoop of coffee grounds into a coffee filter and tie it up with dental floss. When you’re ready to brew, just make it like you would make tea in a teabag!
15. Need your coffee? Bring a few of these.
They’ll keep you from going into caffeine withdrawal.
17. Make single-use soap leaves from a bar of soap and a vegetable peeler.
You can also rub soap on mosquito bites to relieve the itchiness.
18. Use an empty laundry detergent dispenser as a hand-washing station.
Just fill it up with water.
22. Make pancakes with pre-made pancake mix using shortening and dry milk, which don’t need to be refrigerated.
Get the full recipe here. You can also find powdered eggs at most grocery stores (if you don’t shudder at the thought).
23. Put a battery-powered votive candle into an empty peanut butter container to make portable lanterns.
25. Make an easy-to-carry fire starter with a cardboard-only egg carton and match light charcoal.
You just have to light the carton and the fire will catch on to the charcoal.
27. Make pocket-sized oil lamps out of travel-size or hotel toiletry shampoo bottles.
Get the directions here.
28. Forgo the meat marinade and put the rosemary right on the coals.
Once the coals are uniformly gray and ashy, cover them with fresh rosemary branches. Your meat and vegetables will be flavored with the taste of savory herbs.
29. Bring cheeses in waxed packaging as well as hard cheeses.
Aged cheddar, Parmigiano, and/or Gruyère will keep for at least a week unrefrigerated.
31. Try roasting Starburst.
Sounds crazy, but it’s actually delicious. Crunchy on the outside, warm and gooey on the inside. Roast it until it’s bubbling.
32. Forgo pasta for a quick-cooking alternatives like polenta, quinoa, or couscous.
Polenta is especially versatile because it can be shaped into patties and pan-fried for a sweet or savory meal. Get a recipe for grilled polenta cakes.
33. Cook cinnabuns (the canned kind) in a hollowed-out orange over a campfire.

35. Keep the kids busy with a scavenger hunt.
Write the items down on a paper bag so they have a receptacle for the items.
39. Freeze gallon jugs of water and place them in your cooler.
They’ll keep your food cold, and you’ll have plenty of water to drink for later.
Other things you can freeze to use for later: pasta sauces, chili, and pesto.
40. Make emergency light sources out of an Altoids tin, cardboard, and wax.
