This short movie of Helmholtz-Zentrum Berlin due to ist 10th anniversary was presented live on 18 February in the Tipi at the Chancellery. Now it can be seen publicly. In the midst of large halls, full of glittering machines or in laboratories where people wear blue protective clothes and hoods on their heads, we see the protagonists of the film. They let us feel the joy when they tinker with something new. One of them is Beatriz Roldan Cuenya (6:35 – 7:28).
