Another quick funny German thing

I love ice in my drinks right? So I get here and they don´t have ice makers. Know what they have? Kind of like ziploc baggies, that you put water in the top and it goes down into little open areas in the bag. It´s hard to explain but I am bringing some home with me when I come. But you just put them in the freezer and then when they are ready you put the two sides of the bag apart and you have ice. Natalie had ones that are heart shaped.. it´s cute.
