This is a bottle cap tripod. The screw-on tripod adapter has been integrated onto the top of standard soda bottle caps. Sometimes even the smallest mini tripods can be a pain in the ass to carry around all day, but these could easily fit into any camera bag and then turn an 20oz or even two-liter bottle into a convenient tripod. A very innovative idea, but at $20 each, you may want to look into making one of these yourself.
