Yodobashi’s $24.99 Bottle Cap Tripod fits that need admirably. One side screws onto your average plastic bottle (with a cap diameter between 28.5 and 30.5mm), the other side has a standard mounting screw for digital cameras. Pop it on your handy bottle of, er, pop (or water, if you prefer), and you can take steady pictures. You probably want to make sure the bottle is still partially full, though, else the weight of the camera might cause a problem. The whole thing is hardly bigger than a bottle cap, too, so it’s easy to throw in a bag or purse and forget about it.
