A definite camping essential is glow sticks! Each year we bring them on our camping adventure, they become jewelry, headdresses, limbo bars, jump ropes, you name it, a glow stick can become it! These packs are awesome because the sizes vary.
Each night when the sun sets and the s'mores are roasted, pull these babies out and set your camera to a setting without the flash. Keep the camera steady, it'll take a few seconds for the shutter to close, but the end result is pretty awesome.
