These are Stroodles: vegan, flavorless, edible biodegradable drinking straws made out of pasta. Simple enough. They'll allegedly stay rigid for at least an hour in a cold drink, and won't wind up in the nose of some poor sea turtle. A pack of a hundred costs £13 (~$17). Alternatively, buy a pasta extruder and make your own at home. Or go to the grocery store and buy a box of penne pasta like I just did. "Those are pretty short straws, GW." It's cool, I only drink shots anyways.
Thanks to Andrea, who agrees somebody should make hot dog straws.
