Answer 1

Water has an amazing property, like other substances it contracts when cooled but only up to 4 degree Celsius after that, on further cooling it starts expanding. When it reaches the freezing point water expands nearly 9% whereas the cold drink bottles keeps on contracting. Due to lack of space for the expansion in volume ice, the bottle breaks.
