We noticed that the mineral water bottles were easily mixed up when gathering ,so we thought out a method to help us mark our own bottle ,which is changing the processing method of the wrapping paper to create some jags on it ,which helps us tear the paper easily .After opening bottles ,we can tear down one piece of the wrapping paper at random .In this way ,everybody's bottle can be marked differently by the differen shapes of the wrapping paper ,so that we can easily recognize our own bottle which helps save water.
