Bottle flipping is the act of throwing a plastic bottle, typically partially whole of liquid, into the air so that it rotates in an attempt to land it upright on its base or cap. It became an international trend in the summer of 2016, with numerous videos of people attempting the activity being posted online. With its popularity, the repetitive thuds of multiple attempts have been criticized as a distraction and a public nuisance. Parents and teachers have expressed frustration at the practice, resulting in water bottle flipping being banned at several schools worldwide and many people calling for the practice only to be performed in private.
