It was a great first day of the third HackWeek with new project ideas and lots of information about coffee. After everybody has ended breakfast, “real” work could start. Some of the colleagues could also work as artists if they like to change their profession some time: they created great creative posters for the Project Fair by drawing their idea with pen and paper. Many innovators could convince others to join their projects. After a healthy lunch with a variety of six different soups, Open Space offered the possibility to learn something about new topics. As learning and thinking drained the energy, an extra dose of caffeine was needed: Time for the tasty coffee workshop. Two guys from Playground Coffee (a small coffee roaster) showed us how to prepare the perfect cappuccino and answered lots of questions about coffee beans, milk foam and coffee machines.
