Cool Gadgets for Girls: Bottle Cap Tripod

Cost: $10 at charlesandmarie.com

The gimmick: How's this for genius: A camera tripod that not only fits in your pocket but slides onto practically any water bottle cap. The Bottle Cap Tripod, offered by über-cool shopping site Charles & Marie, has a universal adaptor that fits almost any camera, and its little hinge allows for easy swiveling.

What the experts say: Coolest Gadgets points out that the Bottle Cap Tripod, "could easily fit into your pocket, and if you're a big water bottle drinker it won't be hard at all for you to find a bottle to use with this." Oh Gizmo! calls it "a must have for amateur photographers," and "a worthwhile investment" at 10 bucks.

Upside: It's definitely one of those "wow" gizmos you can break out during a dinner party, and it's a very affordable stocking stuffer.

Downside: You'll still need a table or flat surface to stand the bottle, making it not so handy on a steep canyon hike or a rafting trip.
