Epic water bottle flipping challenge
23 September 2016
All it involves is simply flipping a bottle but an American teenager took the internet by storm earlier this year thanks to the now viral video of him flipping a water bottle at his high school talent show.
Last night at Open Evening the mathematics department tried it for themselves, testing different types of bottles filled to different levels to find the optimum conditions for a successful flip.
After tens of thousand of throws by the hundreds who a visited us , 30% full of water was the optimum level for both types of bottle as can be seen in the graphs below.
