what do they do with the bottle caps?
if you live in a state where you receive a nickel or dime for the return of your empty soda bottles, you might want to save up and build yourself a boat. in an old pier building in san francisco, david de rothschild is taking old soda bottles and building himself a 60 foot catamaran. builders take the empties and wash and strip the labels. then the two liter soda bottles are filled with dry ice powder. the carbon dioxide from the dry ice makes the bottle rigid so the plastic is reusable. except for the metal masts, all the parts will be made of recycled plastic. de rothschild is planning on sailing his boat from california to austrila in april when construction is complete.
