Bring Less Tape from Camping Hacks
Folgers Toilet Paper Holder
Speaking of toilet paper, taking TP camping can be quite a hassle. Keeping it dry and stored safely but still accessable seems impossible, but here's a solution. Use a Folgers coffee can to store the TP. Slit a hole through the side and the paper can come out, while the roll stays dry inside.
Soda Can Stove
Use a soda can to make a handy, inexpensive stove. All you need is a can, knife, and alcohol for fuel. This video tutorial shows you how. It can be dangerous, so be careful.
Ziploc Bag Hacks
There are so many ziploc bag hacks, it's hard to name them all. A few that I've found useful are food storage, pancake mix storage (you can then cut the corner and squeeze right out), and my personal favorite, a ziploc pillow. Just blow up the bag, seal it shut, and snooze comfortably.
