This is a Kickstarter project that creates cheap, and high-quality straws and bowls out of bamboo, and coconut. They can be produced very easily, but also are biodegradable, as they are 100% created out of bamboo and coconut. These straws and bowls could be distributed in place of plastic straws and cups, or at marathons.
