An idea so simple I'm wondering why I didn't think of it myself. A Bottle Top Tripod called "Snaps On A Bottle"! Need to steady your camera but don't want to lug around a cumbersome tripod? Just pop a Snaps On A Bottle into your pocket and you're all set. Incredibly convenient and guaranteed to help turn you into a master photographer (well, hopefully!). The Snaps On A Bottle screws onto a regular PET bottle. It has a height of 1.9 inches.
