In 2013, Malopolska Researchers' Night will be organised for the seventh time. Malopolska Researchers’ Night 2013 will be organised on an unprecedented scale thanks to the involvement of 24 Partners (both consortium and non-consortium members) and 24 collaborating institutions. On 27 September 2013, all present and future lovers of science are invited to join researchers in the four regional towns and cities participating in the project, i.e. Krakow, Tarnow, Nowy Sacz and Niepolomice, and explore the secrets of the research profession or just have fun playing with science. A record number of ca. 700 researchers and ca. 500 students (a total of 1,300!) as well as over 60 students’ associations have offered to assist with the project. Apart from the Partners participating in previous years of the project, new institutions, faculties and departments have joined this year’s project. Attractions such as ca. 150 workshops, 180 shows and demonstrations, over 100 lectures and guided tours of nearly 60 laboratories will await those who visit one of the 42 locations participating in Malopolska Researchers' Night 2013. Lovers of puzzles will have a choice of ca. 35 competitions and quizzes and children will be invited to ca. 25 games with researchers. Malopolska Researchers' Night 2013 will offer an opportunity to demonstrate not only what researchers do at work but also what they do in their free time. There will be exhibitions, theatre plays featuring researchers as actors, meetings and discussions over a cup of coffee and a talk show with researchers. Given the wide and varied programme of attractions, the participation of new institutions and the lessons learned from the six previous years of the project (it attracted 46,000 people last year) it is estimated that over 55,000 people will participate in Malopolska Researchers' Night 2013. A professionally prepared and intensive awareness campaign will reach nearly 3 million people with information about the event.
